Behavior change, weight loss, and physiological improvements in Type II diabetic patients.

53 obese 30–70 yr olds with Type 2 diabetes treated by diet only or oral medication were assigned to a behavior-modification, nutrition-education, or standard-care treatment condition to investigate whether behavior modification would improve short- and long-term results of weight control programs for Ss. The behavior-modification and nutrition-education groups met weekly for 16 wks and were given the same information on nutrition, exercise, and diabetes; however, strategies to change eating behavior were used in the behavior-modification condition. The standard-care condition was identical to the nutrition-education condition except that Ss met only 4 times over the 16-wk treatment period. Results indicate that behavior-modification Ss lost more weight than either the nutrition-education or standard-care Ss during the 16-wk treatment period. However, at 16-mo follow-up, differences in weight loss across treatment conditions were not significant. Physiological parameters and mood improved with initial weight loss, but these changes were not maintained. Physiological changes appeared more directly related to weight loss than to treatment condition. Changes in weight were related to improved eating and exercise habits, and modest weight losses of 4.6–23.6 kg produced significant improvements in blood-sugar control.

Long-term effects of interventions for weight loss using food provision and monetary incentives.

One hundred seventy-seven men and women who had participated in an 18-month trial of behavioral interventions involving food provision and financial incentives were examined 12 months later. Food provision, but not financial incentives, led to better weight loss than standard behavioral treatment during the 18-month trial, but over 12 additional months of no-treatment follow-up, all treated groups gained weight, maintained only slightly better weight losses than a no-treatment control group, and did not differ from each other. Weight loss success during both active treatment and maintenance was associated with increase in exercise, decrease in percentage of energy from fat, increase in nutrition knowledge, and decrease in perceived barriers to adherence. Obesity treatment research should focus on developing better ways to maintain changes in the diet and exercise behaviors needed for sustained weight loss.

The effects of health beliefs on weight loss in individuals at high risk for NIDDM

OBJECTIVE: To determine whether perceived risk and other health beliefs held by individuals at high risk for developing NIDDM predict weight loss and behavior change during a behavioral weight loss program to reduce the risk of NIDDM. RESEARCH DESIGN AND METHODS: Health beliefs and objective risk factors for diabetes were examined in 154 overweight men and women with a family history of NIDDM. The effects of these factors on adherence, dietary intake, weight loss, and changes in glucose levels were examined in a subset of 79 of these subjects who participated in a 2-year behavioral weight control program. RESULTS: Those subjects who perceived themselves at highest risk of developing diabetes had a stronger family history of the disease and were more likely to be women than subjects considering themselves at more moderate risk. These participants also rated diabetes as a more serious disease, but were less likely to believe that weight loss would lower their risk. None of these health beliefs were related to attendance at meetings, dietary intake, weight loss, or fasting glucose, but higher perceived seriousness predicted larger reductions in BMI at 1 year. Of the objective risk factors for NIDDM, higher baseline BMI predicted larger weight losses throughout the program, and a stronger family history of diabetes was related to greater weight regain after an initial weight loss. CONCLUSIONS: Perceived risk of developing diabetes and other health beliefs did not predict performance in a behavioral weight loss program. These data suggest that efforts to modify health beliefs by educating high-risk individuals about their risk and benefits of weight loss may not be effective in improving long-term weight loss results.     

Role of orlistat in the treatment of obese patients with type 2 diabetes. A 1-year randomized double-blind study

OBJECTIVE: Obesity is an important risk factor for type 2 diabetes. Weight loss in patients with type 2 diabetes is associated with improved glycemic control and reduced cardiovascular disease risk factors, but weight loss is notably difficult to achieve and sustain with caloric restriction and exercise. The purpose of this study was to assess the impact of treatment with orlistat, a pancreatic lipase inhibitor, on weight loss, glycemic control, and serum lipid levels in obese patients with type 2 diabetes on sulfonylurea medications. RESEARCH DESIGN AND METHODS: In a multicenter 57-week randomized double-blind placebo-controlled study, 120 mg orlistat or placebo was administered orally three times a day with a mildly hypocaloric diet to 391 obese men and women with type 2 diabetes who were aged > 18 years, had a BMI of 28-40 kg/m2, and were clinically stable on oral sulfonylureas. Changes in body weight, glycemic control, lipid levels, and drug tolerability were measured. RESULTS: After 1 year of treatment, the orlistat group lost 6.2 +/- 0.45% (mean +/- SEM) of initial body weight vs. 4.3 +/- 0.49% in the placebo group (P < 0.001). Twice as many patients receiving orlistat (49 vs. 23%) lost > or = 5% of initial body weight (P < 0.001). Orlistat treatment plus diet compared with placebo plus diet was associated with significant improvement in glycemic control, as reflected in decreases in HbA1c (P < 0.001) and fasting plasma glucose (P < 0.001) and in dosage reductions of oral sulfonylurea medication (P < 0.01). Orlistat therapy also resulted in significantly greater improvements than placebo in several lipid parameters, namely, greater reductions in total cholesterol, (P < 0.001), LDL cholesterol (P < 0.001), triglycerides (P < 0.05), apolipoprotein B (P < 0.001), and the LDL-to-HDL cholesterol ratio (P < 0.001). Mild to moderate and transient gastrointestinal events were reported with orlistat therapy, although their association with study withdrawal was low. Fat-soluble vitamin levels generally remained within the reference range, and vitamin supplementation was required in only a few patients. CONCLUSIONS: Orlistat is an effective treatment modality in obese patients with type 2 diabetes with respect to clinically meaningful weight loss and maintenance of weight loss, improved glycemic control, and improved lipid profile.     

Lifestyle intervention in people with insulin-dependent diabetes mellitus (IDDM)

OBJECTIVE: To investigate the impact of intensive lifestyle education on dietary practices, exercise and metabolic measurements in people with insulin-dependent diabetes mellitus (IDDM). DESIGN: Sixty-one volunteer subjects with IDDM were randomised to intensive (Group 1) or standard (Group 2) education programmes for six months. During a second six month period of observation Group 1 subjects received routine surveillance for their condition and those in Group 2 were given intensive advice (phase 2). Current insulin regimens were modified to optimise glycaemic control before the start of the intervention phase. Nutrient intakes, weight, blood pressure, glycated haemoglobin (HbA1), plasma lipids, lipoproteins and maximal oxygen consumption (VO2 max) were measured at the time of recruitment and at three monthly intervals during the trial and phase 2. SETTING: Department of Human Nutrition at the University of Otago. RESULTS: Glycated haemoglobin decreased significantly in both groups between recruitment and randomisation, the improvement being sustained during the six months of the randomised trial and for group 1 during the six months of post trial observation. A further decrease was seen in Group 2 during the second six month period when they were given intensive advice. Comparable changes were seen with total and low density lipoprotein (LDL) cholesterol in Group 1 during the trial, but significant decreases were only seen in Group 2 in association with intensive intervention (phase 2). These changes occurred in parallel with increases in intakes of carbohydrate and monounsaturated fatty acids, a reduction in intakes of total and saturated fat, and an improvement in maximum oxygen consumption. CONCLUSIONS: A lifestyle programme for people with IDDM results in modest changes in diet and exercise habits sufficient to improve measures of glycaemic control and lipoprotein mediated risk of coronary heart disease independent of changes in insulin regime. More innovative approaches to achieve lifestyle changes are required to meet current recommendations which in turn are likely to produce even greater beneficial changes than those observed here.     

Effects of group- versus home-based exercise in the treatment of obesity.

This study examined the effects of 2 aerobic exercise regimens on exercise participation, fitness, eating patterns, treatment adherence, and weight changes in 49 obese women undergoing a year-long behavioral weight loss program. Participants were assigned randomly to weight loss treatment plus either group- or home-based exercise. All participants were instructed to complete a moderate-intensity walking program (30 min/day, 5 days/week). Group exercise participants were provided with 3 supervised group exercise sessions per week for the 1st 26 weeks and with 2 sessions per week thereafter. Home exercise participants were instructed to complete all exercise in their home environment. After 6 months, both conditions displayed significant improvements in exercise participation, fitness, eating patterns, and weight loss. At 12 months, the home-based program showed superior performance to the group condition in exercise participation and treatment adherence; at 15 months, participants in the home program demonstrated significantly greater weight losses than those in the group program.

Weight loss and maintenance and changes in diet and exercise for behavioral counseling and nutrition education.

100 out of 112 women who initially were at least 20 lb overweight, but did not weigh over 220 lb completed a 16-wk program of either behavioral counseling or nutrition education. Initial weight losses were similar for both groups, but behavioral Ss (BEs) consumed significantly fewer calories and changed more on 2 of 4 exercise measures than did nutrition education Ss (NEs). Reviews of daily eating records indicated that BEs more often used diets that were nutritionally unsound. The exercise changes in both conditions were modest and highly variable. Seven-month follow-up indicated that BEs maintained significantly more weight loss than did NEs. Interviews with 92 Ss indicated that regular monitoring of eating, an exercise routine, and problem solving were associated with maintenance.

Effects of diet plus exercise on weight change in parents and children.

Obese children (aged 8–12 yrs) and parents from 53 families were randomly assigned to 3 groups: diet, diet plus exercise, and no-treatment control. At 6 mo, parents and children in both treatment groups had equal and significantly better weight change than members of the control group. At 1 yr, however, parents given diet plus exercise showed better weight losses than parents given diet alone. No treatment group differences were found for children after 1 yr. Parent and child weight changes observed during the 1st 6 mo of treatment were highly correlated, but those observed during Months 6–22 were uncorrelated. Discriminant analyses showed that initial relative weight was the best predictor of 12-mo relative weight for both parents and children but that exposure to the exercise program during treatment was a predictor of maintenance of nonobesity.

The effect of antiemetics and reduced radiation fields on acute gastrointestinal morbidity of adjuvant radiotherapy in stage I seminoma of the testis: a randomized pilot study

OBJECTIVE: To assess the long term effects of weight loss with and without additional aerobic and weight training exercises on exercise tolerance and cardiorespiratory fitness in obese women. EXPERIMENTAL DESIGN: Randomized prospective study for an approximately one-year community setting. PATIENTS: 31 healthy obese women volunteers (age 42.8 yrs +/- 6 SD) recruited by community advertisement. INTERVENTION: All subjects underwent a weight loss program consisting of low calorie diet and behavior therapy for a minimum of 46 weeks. They were randomly assigned to one of the four groups. Group A: diet alone, Group B: diet plus aerobic exercise program in a supervised group setting, Group C: Diet plus weight training and Group D: diet plus weight training plus aerobic exercise program. MEASURES: Exercise time (Tex) peak sustained workload (Wp), peak oxygen consumption (VO2), oxygen pulse and the rate of change of VO2 on recovery (VO2rec) were measured at the beginning and after 47.5 weeks +/- 1.5 SD, of the program. RESULTS: All subjects lost weight and achieved increased Tex and lowered resting VO2. VO2 peak and VO2 peak kg-1 increase in Groups B and D only. O2 pulse and VO2rec improved in group D. Improvements in exercise time correlated significantly with initial exercise time and weight loss. CONCLUSIONS: Weight loss increase Tex irrespective of participation in an exercise program. However, evidence of improved aerobic fitness occurred only in groups performing aerobic exercise.     

History of maternal fetal loss and increased risk of childhood acute leukemia at an early age. A report from the Childrens Cancer Group

BACKGROUND: Maternal reproductive history of fetal loss previously has been reported to be associated with an increased risk of leukemia in subsequent offspring. Data from a Childrens Cancer Group (CCG) case-control study were analyzed to test the hypothesis that this association was dependent on the number of previous fetal losses and age at leukemia diagnosis. METHODS: A case-control study using a large Childrens Cancer Group database examined maternal history of fetal loss as a risk factor for childhood leukemia in subsequent offspring. One thousand seven hundred fifty-three patients with childhood acute leukemia were compared with 839 community control subjects s and 2081 nonleukemia cancer control subjects. RESULTS: A modest increase in risk was found to be associated with a history of fetal loss. Stratification by age at diagnosis of leukemia showed that this association was significant only for those patients diagnosed before 4 years of age and most significant in those patients diagnosed before 2 years of age. When comparing community controls with patients acute lymphocytic leukemia diagnosed before 2 years of age, one previous fetal loss was associated with a five-fold increased risk (P < 0.001) whereas two or more fetal losses were associated with a relative risk of 24.8 (P < 0.001). Similarly, patients with acute myelocytic leukemia diagnosed before 2 years of age demonstrated 5-fold and 12-fold increased risks associated with the previous fetal loss and 2 or more previous fetal losses, respectively. CONCLUSIONS: Childhood acute leukemia occurring at younger ages may be associated with an underlying genetic abnormality or chronic environmental exposure, which can be either lethal to the developing fetus or mutagenic and result in the development of acute leukemia.     

Weight change in relation to intake of sugar and sweet foods before and after weight reducing gastric surgery

OBJECTIVE: To test the hypothesis that a diet containing many sweet foods is associated with poor weight loss after gastroplasty. SUBJECTS AND METHODS: 375 severely obese subjects followed for 2 y after vertical banded gastroplasty or gastric banding; 34 subjects followed after gastric bypass. RESULTS: Total energy and all macronutrients were reduced 2 y after surgery. Sweet foods were less reduced than other foods, resulting in a relative increase of sugar intake. At 2 y a high relative intake of sugar and fat was associated with a low energy intake and a large weight reduction in the gastroplasty group. In the highest quartile of mono+disaccharide intake (> 142 g) weight loss was 29.9 kg compared to 25.1 kg in lowest quartile (> 72 g). Absolute and relative sugar intake before surgery did not predict weight outcome. At 6 months, i.e. during a period of active weight reduction, energy intake was significantly related to weight loss. CONCLUSION: Gastroplasty patients who continue selecting sweet foods appear to maintain lower energy intakes and lose more weight. However the associations are unlikely to be causal but probably indicative of changes in other aspects of the diet, eg exclusion of regular meals. Since large weight losses are most likely to be associated with low quality diets these results highlight the need for supplementation therapy of gastroplasty patients. Finally the lack of association between presurgical sugar intake and subsequent weight loss brings into question the surgical practice of selectively assigning sweet eaters to gastric bypass.     

Diet and exercise intervention have favourable effects on blood pressure in mild hypertensives: the Oslo Diet and Exercise Study (ODES)

The purpose of this study was to investigate the effect of 1-year diet intervention, exercise intervention and both combined on blood pressure (BP) in normotensives and mild hypertensives. Two hundred and nineteen sedentary middle aged men and women with slightly deranged coronary heart disease (CHD) risk factors were randomised to a control, a diet, an exercise and a diet + exercise group. Based on baseline diastolic BP, participants were divided into tertiles, giving baseline average BP of 141.4/96.7 in tertile 1, 130.7/87.6 in tertile 2 and 121.9/79.0 in tertile 3. The 1-year net-difference in BP between the intervention groups and the control group decreased across the tertiles; in tertile 1 being -11.2/-6.7 (p < 0.05), -11.3/-6.7 (p < 0.05 for systolic BP only) and -7.0/-5.1 (NS) in the combined, diet and exercise group respectively. Triglycerides, HDL cholesterol, and insulin variables were significantly and favourably changed, the changes being most marked in the combined group. The results show that diet and diet + exercise are about equally effective in reducing BP, and the effects may be dependent on the baseline level. Within the upper tertile of baseline BP, the decline in BP in the combined intervention and the diet group are almost comparable to those obtained with drug treatment. In addition, other important CHD risk factors were all changed in a beneficial direction.     

Exercise and the maintenance of weight loss: 1-year follow-up of a controlled clinical trial.

This study reports results 1 year after treatment for 77 obese women who had been treated for 48 weeks by diet combined with supervised (a) aerobic exercise, (b) strength training, (c) aerobic plus strength training combined, or (d) no exercise. Mean (± SD) end-of-treatment weight losses for the 4 conditions ranged from 13.5?±?9.1 kg to 17.3?±?10.3 kg, but there were no statistically significant differences among groups. Participants in all 4 conditions regained approximately 35% to 55% of their weight loss in the year after treatment; again, there were no significant differences among groups. Participants, however, who reported exercising regularly in the 4 months preceding the follow-up assessment regained significantly less weight than did nonexercisers.

Transverse myelitis. Comparison with spinal cord presentations of multiple sclerosis

This study reports results 1 year after treatment for 77 obese women who had been treated for 48 weeks by diet combined with supervised (a) aerobic exercise, (b) strength training, (c) aerobic plus strength training combined, or (d) no exercise. Mean (+/- SD) end-of-treatment weight losses for the 4 conditions ranged from 13.5 +/- 9.1 kg to 17.3 +/- 10.3 kg, but there were no statistically significant differences among groups. Participants in all 4 conditions regained approximately 35% to 55% of their weight loss in the year after treatment; again, there were no significant differences among groups. Participants, however, who reported exercising regularly in the 4 months preceding the follow-up assessment regained significantly less weight than did nonexercisers.     

Bone loss associated with a high fibre weight reduction diet in postmenopausal women

OBJECTIVE: To examine the effect of high fibre weight reduction on bone density in postmenopausal women. DESIGN: Case-control study. SETTING: Hospital outpatient dietetic clinic and Osteoporosis Screening Unit. SUBJECTS AND INTERVENTIONS: Sixteen overweight volunteers who followed a high fibre reducing diet for 6 months, to lose 20% of excess body weight (above body mass index 25 kg/m2), and returned to their starting weight by the end of a further 6 months. Forty-six non-dieting controls, matched for age and years postmenopause, selected from screening unit volunteer register. RESULTS: Annual percentage changes in lumbar spine bone mineral density, measured by dual energy X-ray absorptiometry were: controls -2.5% (SE 0.5), dieters -4.8% (0.9), 95% confidence interval of difference between groups -0.2 to -4.3% (P = 0.03); femoral neck bone density controls -2.5% (0.5), dieters -2.1% (0.9), 95% confidence interval of difference -1.7 to 2.5% (P = 0.69). CONCLUSIONS: High fibre weight reduction in postmenopausal women significantly increased annual bone loss from the lumbar spine. This loss was not reversed by weight regain in the second 6 months. Repeated cycles of high fibre weight loss and weight gain may increase the risk of spinal osteoporosis.     

Long-term drug treatment of obesity in a private practice setting

This study evaluated the long-term efficacy and safety of the combination of phentermine and fenfluramine for the treatment of obesity in a private practice setting. A total of 1388 consecutive, qualified patients presenting to a private general internal medicine practice in Charlotte, NC, were enrolled with eligibility criteria including: age 18 years to 60 years, 20% over "desirable" bodyweight or body mass index > 27, no serious medical or psychiatric disease, and no contraindications to drug therapy. Patients were instructed in diet, exercise, and behavior modification techniques and received phentermine (15 mg/day to 30 mg/day) and fenfluramine (20 mg/day to 60 mg/day) continuously for over 3 years. Average duration of treatment was 15.9 months, and average weight loss at the last visit was 11.6 kg, or 11.7% of initial bodyweight. For patients completing 1 year of drug treatment, mean weight loss was 16.5 kg, or 16% of initial weight. Weight loss persisted for 2 years, but partial regain was seen at 3 years. The dropout rates were 18% at 6 months, 39% at 1 year, 68% at 2 years, and 78% at 3 years. At 1 year, blood pressure of hypertensive patients fell from 151/95 mm Hg to 127/78 mm Hg, and serum cholesterol and triglycerides of hyperlipidemic patient fell by 0.750 mmol/L (29 mg/dL) and 0.937 mmol/L (83 mg/dL), respectively. Adverse events were modest. We conclude that, in a private practice setting, long-term treatment of obesity with the combination of phentermine, fenfluramine, and a weight maintenance program is generally safe and effective. More research is needed to determine efficacy and safety for longer than 3 years.     

Prediction of growth sensitivity of acute promyelocytic leukemia cells to granulocyte colony-stimulating factor using 7AAD/PY during administration of all-trans retinoic acid

OBJECTIVE: The traditional goal of obesity therapy has been the reduction of body weight to an ideal standard. Patient difficulties, however, in reaching this goal have led to a reassessment of weight loss criteria. The Institute of Medicine of the National Academy of Sciences recently proposed that successful long-term weight loss be defined as the reduction of initial weight by 5% or more and the maintenance of this loss for at least 1 year. The present study used these criteria to evaluate the long-term efficacy of a proprietary weight loss program. METHODS: Patients were 621 persons who had completed a 26-week weight loss program that included 12 weeks of treatment by a very-low-calorie diet. They were recruited from a total of 1,283 eligible persons who had been treated at 36 clinics nationwide. Clinics were randomly selected to participate. Patients' weights were determined in telephone interviews initially conducted 2 years after treatment and then at yearly intervals through 5 years of follow-up. RESULTS: At the end of treatment, men achieved a mean reduction in initial weight of 25.5 +/- 1% and women 22.6 +/- 1%. Subjects regained substantial amounts of weight by the 2-year follow-up but 77.5% of men and 59.9% of women still maintained losses of 5% or more of body weight. At the 3-year follow-up, 53% of the original sample (of 621 persons) maintained losses of 5% or more and 35% losses of 10% or more. These trends were apparent 4 and 5 years after treatment but the dwindling sample sizes prevented definitive assessments. DISCUSSION: The findings showed that a program of lifestyle modification combined with the brief use of a very-low-calorie diet was associated with successful weight control in a substantial portion of patients several years after treatment. Long-term weight losses of 5% or more of initial weight are likely to be associated with improvements in health complications.     

Nondieting versus dieting treatment for overweight binge-eating women.

This study evaluated the effectiveness of nondieting versus dieting treatments for overweight, binge-eating women. Participants (N?=?219) were randomly assigned to 1 of 3 groups: diet treatment (DT), nondiet treatment (NDT), or wait-list control (WLC). DT received a balanced-deficit diet reinforced with behavioral strategies. NDT received therapy designed to help participants break out of their dieting cycles. Treatment in both conditions was administered in weekly groups for 6 months, followed by 26 biweekly maintenance meetings, for a total of 18 months of contact. At 6 months posttreatment, DT lost 0.6 kg while NDT gained 1.3 kg. Both treatment groups reduced their Binge Eating Scale scores significantly more than WLC. At 18-month follow-up, both treatment groups experienced weight gain but maintained similar reductions in binge eating. Results indicate that neither intervention was successful in producing short- or long-term weight loss. Therapist biases, which may have affected treatment integrity, and other methodological issues are discussed in relation to the small weight losses achieved.

Effect of weight loss and refeeding diet composition on anaerobic performance in wrestlers

Collegiate wrestlers (N = 12) consumed a formula, hypoenergy diet (18 kcal.kg-1, 60% carbohydrate) without dehydration for 72 h. For the next 5 h, the athletes were fed either a 75% (HC) or a 47% (MC) carbohydrate formula diet of 21 kcal.kg-1. Each wrestler performed three anaerobic arm ergometer performance tests (TEST1, before weight loss; TEST2, after weight loss; TEST3, after refeeding). Blood withdrawn just before and after each test was analyzed for pH, bicarbonate, base excess, glucose, and lactate. Both groups had a similar significant reduction in total work done during TEST2 (92.4% of TEST1). Work done in TEST3 by HC was 99.1% of TEST1 while MC did 91.5% of their initial work (P = 0.1). Peak power was unaffected by the treatment. Plasma lactate significantly increased during the performance test from 1.72 to 21.91 mmol.l-1 as did plasma glucose from 4.88 to 5.25 mmol.l-1 when groups and trials were collapsed. Lactate accumulation was diminished during TEST2 compared with the other tests. Although the exercise bout reduced pH, bicarbonate, and base excess, there was no difference in the effect by group. In conclusion, weight loss by energy restriction significantly reduced anaerobic performance of wrestlers. Those on a high carbohydrate refeeding diet tended to recover their performance while those on a moderate carbohydrate diet did not. The changes in performance were not explained by the acid/base parameters measured.     

Epidemiologic aspects of the burnout syndrome in hospital personnel

The long-term effects of a 12- and 26-day residential weight control program on weight change were determined in 187 men and women, 1 to 5 years after treatment. Subjects completed a paper/pencil questionnaire assessing current diet, weight control techniques, exercise behaviors, behavior modification techniques, binge eating, and dieting behavior. General linear modeling was used to investigate the association between behaviors maintained posttreatment and current weight among subjects who demonstrated behaviors indicative of binge traits (BT) and nonbinge traits (NBT). Results indicate that dissimilar variables are predictive of weight change in the BT and NBT groups. Engaging in exercise behaviors and reduced attempts at dieting lead to greater weight loss in NBT individuals. The use of preplaning techniques was found to be indicative of greater weight loss in BT individuals. These findings suggest the importance of identifying individuals who indulge in binge-eating behaviors prior to intervention in order to deliver the appropriate treatment methods.
