Smoking prevention and cessation in adolescents

Tobacco smoking is the most important preventable health risk factor in Australia. It has lost popularity and acceptability in Australia as a result of public health campaigns and their reinforcement through government legislation. The rate of smoking in Australia has gradually declined due to increased cessation in adults. Adolescents, however, are smoking as much as ever. The aim of this paper is to provide family practitioners with practical, simple clinical strategies to reduce teenage smoking.     

Smoking and nicotine addiction: a pediatric epidemic with sequelae in adulthood

Pediatric addiction to nicotine from cigarette smoking is a major public health problem, extracting a tremendous societal toll in terms of human suffering, a loss of future productivity, and the consumption of scarce health care resources. Teenagers smoke 1.1 billion packs of cigarettes yearly and will account for more than $200 billion in future health care costs. Recent behavioral studies confirm nicotine's ability to induce in adolescents both the tolerance and abstinence phenomena typical of other addicting substances. A range of adverse health effects, first detectable in adolescent cigarette smokers, extend into adulthood. Through the effects of environmental smoke or smoking during pregnancy, adolescent smokers affect not only their own health, but that of friends, family members, and even their own fetuses and children. Additional research into effective prevention and smoking cessation programs is urgently needed to forestall the ravaging of yet another generation by this preventable and deadly habit.     

Architecture. HOTELIA, an innovative concept

This article focuses on adolescent pregnancy and birth issues in the US. Although the birth rate among adolescents aged 10-19 years in New Jersey declined to 9609 infants per year in 1994, a decline of 7% from 1990, there remain concerns about the welfare of the mother and fetal development. Adolescent birth rates in New Jersey are higher for Black youths compared to White youths (100/1000 births vs. 25.4/1000). During 1990-94, births to girls aged 10-14 years increased from 241 to 284. There are many reasons for teenage pregnancy: abuse or coercion, peer pressure, misinformation, defiant behavior, person whims, and need for success through pregnancy. Pregnant teens frequently do not receive adequate prenatal care, maintain good nutrition, and/or refrain from unhealthy habits such as cigarette smoking, alcohol drinking, and/or drug use. The lack of prenatal care until late pregnancy may be due to lack of health insurance coverage or money for transportation. Teenagers have higher rates of premature births. Fetal development may be impaired due to lack of a proper maternal diet with a sufficient amount of folic acid, iron and protein, or food intake. Teenagers have twice the rate of spina bifida. Girls need to know the facts about the risk of premature birth and low birth weight associated with their cigarette smoking during pregnancy. Girls should be asked to reduce smoking to 3-5 cigarettes per week by the next visit and to stop entirely by the following visit. Teenagers need reinforcement in adopting the right eating patterns and curbing undesirable habits. Prenatal care should be comprehensive. The evidence suggests that fetal development is hampered by the competition for resources between the mother and fetus. Health care professionals must provide contraceptives and education; most hope that the repetitive cycle of repeat pregnancy and poverty does not continue.     

Syme amputation: results in patients with severe forefoot ischemia

Teenage pregnancy has become a serious public health problem, particularly in developing countries with limited obstetric facilities. The condition has often been associated with obstetric and gynaecological risks. The present study which attempts to identify such risks has revealed teenage pregnancy an an important public health problem in Nigeria. Out of 4,649 pregnant mothers followed up in an antenatal clinic of a general hospital, 704 (15.1%) were teenagers. The highest frequency of low birth weight babies was recorded amongst these teenage mothers; so also was anaemia. In addition, the number of stillbirths and the incidence of low birth-weight babies were found to increased with decreasing maternal haemoglobin level. As a result of the identified risk factors associated with teenage pregnancy, it is suggested that teenage pregnant mothers be given more specialised supervision during antenatal period and at delivery; while efforts should be made to reduce the incidence of teenage pregnancy through scholarship programs for the education of girls.     

Health, health promotion and the elderly

Health promotion is a mode of practice which is being increasingly examined by policymakers (DHSS, 1987; DoH, 1992). Although practitioners are being required to screen people over 75 years of age and are exhorted to reduce accidents in the elderly by 33% between 1990 and 2005 (DoH, 1992), there is evidence that they do not value this sort of work (Pursey & Luker, 1993). This paper looks at the findings from 178 interviews with people aged over 75 years, examining the importance of health and health promotion to the elderly. Further to the work of Cox et al. (1987), it is clear that people aged over 75 years continue to engage in a wide variety of activities which are designed to keep or improve their health. Elderly people's accounts of their health suggest that the real influence of social circumstances and environment must be assessed and planned for if health promotion activity is to have relevance and meaning to this group of people. Evidence is presented which indicates that the elderly are a group of people who would welcome health-promotion activity provided it is given in easily accessible forms. The notion of client participation is highlighted as a difficult area, which is likely to require particular skill in working with elderly clients. In the light of these findings, practitioners may need to examine their own attitudes to their work with the elderly.     

Perceptions of urban versus rural hospital patients about return to their communities

During a two-month period in 1976, male patients scheduled to be discharged from two Veterans Administration Hospitals, who were aged 55 or older, chronically ill, able to communicate rationally, and had been hospitalized at least a week for the current illness, were interviewed prior to discharge. Information was sought regarding their feelings about admission and discharge, the availability of and their need for 13 related health-related services at home, and the informal support systems available to them in their local communities. Comparisons were made between patients from distinctly rural settings (communities with less than 5,000 population) and those from larger towns or cities. Both urban and rural patients were modest in assessment of their own health-related needs, especially their need for social and ancillary health services. In almost all instances, the perceived availability exceeded perceived needs. Rural dwellers reported somewhat less apprehension about entering the hospital; they also reported more social contact in their home communities despite the fact that in this sample the rural dwellers were more likely to be older, widowed, and living alone. Rural dwellers were slightly more likely to have their own family doctor.     

Changing nature of physician licensure. Implications for medical education in California

The mortality and morbidity burden of Non-Hodgkin's lymphoma (NHL) is increasing within the human immunodeficiency virus- (HIV-) infected population. Recent improvements in HIV management has meant overall reductions in deaths, especially those due to opportunistic infections, and while the outcome of HIV-related NHL may now be somewhat less grim, the incidence remains high and outcome poor. The median survival of those with HIV-related NHL is only approximately 7 months, although those with high CD4 lymphocyte counts seem to do somewhat better. Improved management of the underlying HIV infection, more effective infusional chemotherapy regimens, moderately effective second line regimens, and new investigational approaches all offer promising hope that improvements will soon be seen for the treatment of HIV-related systemic NHL. Immunotherapy, monoclonal antibodies, and adoptive immunotherapy targeting Epstein Barr virus (EBV) all represent novel experimental treatment approaches that are becoming possible based on our increased understanding of the pathogenesis of HIV-related lymphoma. Primary central nervous system lymphoma (PCNSL) in HIV patients has declined in incidence and there now is a rapid, less invasive diagnostic test. The presence of EBV DNA in the cerebral spinal fluid of HIV patients with focal brain lesions strongly suggests a diagnosis of PCNSL. Unfortunately, this disease remains difficult to treat in such an immunocompromised patient population. Further work is needed in order to prevent and effectively manage these diseases.     

A comparison of the socio-demographic and clinical characteristics of private household and communal establishment residents in a multi-ethnic inner-city area

This study compares the socio-demographic, physical and psychiatric profiles of representative samples of adults resident in communal establishments (n = 170) with those living in private households (n = 544) in a deprived multi-ethnic inner-city health district. Respondents were interviewed about their psychiatric and physical health as well as their early life experiences, close personal relationships, experiences of police contact and episodes of deliberate self-harm. Communal establishment residents were more likely to be single, white men and to be out of work than those in the private household sample. They typically left school at an earlier age, had a more disrupted upbringing, were less likely to have close personal relationships and reported more contact with the police. Both physical and psychiatric morbidity were substantially higher in the communal establishment residents than among those living in private households (especially for psychotic disorders). In contrast to these findings, comparisons between communal establishment residents with and without mental health problems revealed few differences. Our data highlight the extensive needs of those living in communal establishments and the need for a wide range of agencies to co-ordinate their efforts effectively if services to this population are to be effective.     

Arterial hypertension: lessons from patient education

The face of hypertension has been changing rapidly over the last few decades, from a serious disease to a cardiovascular risk factor. Patient education has been instrumental in bringing about tremendous improvements in hypertension-related mortality, morbidity, life expectancy, and life quality. Patient education has evolved from an adjunct to medical therapy to an intervention in its own right. In this process patient education tasks and techniques themselves have undergone remarkable developments, driven by evolving patient needs due to medical progress. The same is true for the roles of patients and health care providers. Dealing with hypertension is a behavior change process which demands serious learning efforts from all parties involved, patients, health practitioners and health care administrators alike. This paper focuses therefore on patient education for preventive behavior change and risk factor management. Special emphasis will be placed on processes and tools for effective patient education.     

Adolescent pregnancy and parenthood: Recent evidence and future directions.

An overview of recent research on adolescent sexual activity, pregnancy, and parenthood is presented, with a focus on the dearth of knowledge concerning psychological precursors and consequences. Although the rate of teenage childbearing has decreased substantially this century, increasing rates of sexual activity, illegitimacy, and welfare receipt raise public concerns. New research is discussed that suggests that many negative outcomes previously ascribed to mothers' age are as much causes or correlates of teenage pregnancy as effects of it, although this claim is less substantiated regarding effects on children of teenage mothers. Literature on fathers and grandmothers is summarized, and suggestions are made for furthering this research. An overview is given of recent successes among intervention programs, and policy implications of the new federal welfare law are considered for teenage mothers and their children.

Parameters of teenage alcohol use: A path analytic conceptual model.

Alcohol use and abuse among adolescents is a serious and complex social problem. Previous research in this area has usually consisted of correlational studies that identified individual factors predictive of teenage drinking. Such simple analytic methods, however, did not allow investigation of interrelations among those parameters that may affect adolescent alcohol use. Also, the lack of comprehensive theoretical models of teenage drinking has handicapped the development of effective intervention strategies. In this study, a large sample of high school students was surveyed to evaluate a theoretical model of teenage drinking with latent-variable path analysis. The results suggested may intricate direct and indirect relations among several classes of variables that powerfully predicted teenage drinking. Implications of these results for future research and for treatment and prevention of teenage alcohol abuse are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The obstetric implications of teenage pregnancy

A retrospective review was performed on the obstetric outcome of teenage pregnancies delivered in 1 year in a tertiary centre. The results were compared with the rest of the obstetric population in the same hospital in the same year. The teenage mothers (n = 194) had increased incidence of sexually transmitted diseases (5.2 versus 1.0%, P < 0.05), and preterm labour (13.0 versus 7.0%, P < 0.01), but decreased incidence of gestational glucose intolerance (3.1 versus 11.4%, P < 0.001), when compared with the non-teenage mothers (n = 4914). There was no difference in the types of labour, while the incidence of Caesarean section was lower (4.1 versus 12.6%, P < 0.001) in the teenage mothers. Although the incidence of low birthweight was higher in the teenage mothers (13.5 versus 6.5%, P < 0.001), there was no significant difference in the mean birthweight, gestation at delivery, incidence of total preterm delivery, or perinatal mortality or morbidity. The results indicate that the major risk associated with teenage pregnancies is preterm labour, but the perinatal outcome is favourable. The good results accomplished in our centre could be attributed to the free and readily available prenatal care and the quality of support from the family or welfare agencies that are involved with the care of teenage mothers.     

Interpreting the new illness question in the UK census for health research on small areas

STUDY OBJECTIVE: The study aimed to identify the various factors that seem to influence the average response to the new census question on limiting, long standing illness at the small area level, to assess the extent to which the new questions adds to information already available in the census and elsewhere, and to discuss how useful the data are likely to be for those planning health and social services. DESIGN: This was a cross sectional analysis of the relationship between rates of limiting, long standing illness (standardised for age and sex) and a large number of indicators of health and socioeconomic status at the small area level. SETTING: The study used data relating to 4985 small areas covering the whole of England. The average population was about 10 000. PARTICIPANTS: The 1991 census of population was addressed to the entire population of England. MAIN RESULTS: There are wide variations in the levels of self reported long standing illness between small areas, 70% of which are explained by demographic factors. Variation in age/sex standardised responses to the new census question at the small area level can largely be explained by census data on self reported disability among those of working age, standardised mortality ratio, and by indicators of socioeconomic circumstances relating to social class, ethnicity, and the elderly living alone. These does not seem to be a significant reporting bias due to underemployment. CONCLUSION: Unlike the disability question in the census, the standardised, self reported long standing limiting illness ratio covers the entire population and it is not skewed towards men. Although the variable is a synthesis of the health and social determinants of perceived morbidity, it does not provide much information that was not already available. In addition, it is available every 10 years only and thus may be rather inaccurate as an indicator of relative need towards the end of the decade. Moreover, in future censuses, individuals' answers might be influenced by the knowledge that their responses will affect the volume of resources allocated to the area in which they live.     

Effect of spinal cord injury on the heart and cardiovascular fitness

The use of various FES protocols to encourage increases in physical activity and to augment physical fitness and reduce heart disease risk is a relatively new, but growing field of investigation. The evidence so far supports its use in improving potential health benefits for patients with SCI. Such benefits may include more efficient and safer cardiac function; greater stimulus for metabolic, cardiovascular, and pulmonary training adaptations; and greater stimulus for skeletal muscle training adaptations. In addition, the availability of relatively inexpensive commercial FES units to elicit muscular contractions, the ease of use of gel-less, reusable electrodes, and the increasing popularity of home and commercial upper body exercise equipment mean that such benefits are likely to be more accessible to the SCI population through increased convenience and decreased cost. The US Department of Health and Human Services has identified those with SCI as a "special population" whose health problems are accentuated, and so need to be specifically addressed. FES presents "a clear opportunity.... For health promotion and disease prevention efforts to improve the health prospects and functional independence of people with disabilities." As a corollary to this, the Centers for Disease Control and Prevention have recommended the development of techniques to prevent or ameliorate secondary disabilities in persons with a SCI. Patients with SCI have an increased susceptibility to cardiac morbidity and mortality in the acute and early stages of their injury. Most of these patients make an excellent adaptation except when confronted with infection or hypoxia. SCI by itself does not promote atherosclerosis; however, in association with multiple secondary conditions related to SCI, along with advancing age, patients with SCI are predisposed to relatively greater risk of heart disease. The epidemiologic significance of this is reflected in demographic studies that indicate an increasing number of SCI patients becoming aged. Currently 71,000 (40%) of the total 179,000 patients with SCI living in the United States are older than 40 years, and 45,000 have injuries sustained more than 20 years earlier. In addition, new injuries in the older population are increasing (currently 11% of all injuries), and some of these new patients with SCI already have pre-existing cardiac disease. Studies have demonstrated that improved lifestyle, physical activity, lipid management, and dietary restrictions can affect major risk factors for coronary artery disease. Therefore an aggressive cardiac prevention program is appropriate for patients with SCI as part of their rehabilitation. At a given submaximal workload, arm exercise is performed at a greater physiologic cost than is leg exercise. At maximal effort, however, physiologic responses are generally greater in leg exercise than arm exercise. Arm exercise is less efficient and less effective than lower body exercise in developing and maintaining both central and peripheral aspects of cardiovascular fitness. The situation is further compounded in SCI because of poor venous return as a result of lower-limb blood pooling, as a result of lack of sympathetic tone, and a diminished or absent venous "muscle pump" in the legs. This latter mechanism perhaps contributes the greatest diminution in the potential for aerobic performance in the SCI population. Obtaining a cardiopulmonary training effect in individuals with SCI is quite possible. Current studies indicate decreases in submaximal HR, respiratory quotient, minute ventilation, and oxygen uptake, with increases in maximal power output, oxygen uptake, minute ventilation, and lactic acid. Individuals with SCI have been shown to benefit from lower limb functional electrical stimulation (FES)-induced exercise. Studies have consistently reported increases in lower limb strength and cycle endurance performance with these protocols, as well as improvements in metabolic and     

Family planning: an essential component of prenatal care

This nation's traditional approach to improving maternal and infant health has been prenatal care. But evidence is mounting that additional progress in reducing maternal and infant morbidity and mortality will depend, at least in part, on the care that a woman receives before she conceives. The studies reviewed in this paper indicate that increasing the interval between deliveries and preventing or delaying pregnancies among women at high risk could lower the rate of low birthweight (LBW). Since reducing the rate of unintended pregnancies would also reduce the number of pregnancies in women at high risk of LBW because of race, age, late or no prenatal care, and unhealthy behaviors, the prevention of unintended pregnancies would also reduce LBW. Unfortunately, prenatal care, as experienced by many women, devotes little attention to these family planning issues. Many women do not realize the importance of family planning to their own health and that of their children. Prenatal care providers should include instruction about the importance of pregnancy planning and encourage women to continue receiving health care between pregnancies. If the health of women and infants is to be improved, society must be willing to provide health services to women of reproductive age even when they are not pregnant.     

Adolescent sexual and reproductive behavior: a review of the evidence from India

Despite the fact that adolescents represent almost one quarter of the Indian population, their reproductive health needs are poorly understood and ill served. This paper documents the existing research on sexual and reproductive health, explores the knowledge and attitudes among this population in India, and highlights limitations of methodologies currently employed in research on adolescent reproductive health in India. One serious limitation is the lack of attention in almost every dimension of their reproductive health, including sexuality, reproductive morbidity, abortion-seeking and reproductive choice. What is needed is more behavioral research that explores the levels, patterns, and sociocultural factors underlying adolescents' reproductive health; assesses adolescent reproductive health needs and ways in which health and information services can be structured to respond to these needs in light of the social, cultural and economic constraints that adolescents face; and explores appropriate methodological alternatives, recognizing the need for community-based research, as well as the difficulties of conducting such research under the sociocultural constraints prevailing in India. At the same time, this review argues for far more attention within programs to address adolescent reproductive health service and information needs.     

Emerging issues in research on lesbians' and gay men's mental health: Does sexual orientation really matter?

Theoretical writings and research suggest that the onset, course, treatment, and prevention of mental disorders among lesbians and gay men differ in important ways from those of other individuals. Recent improvements in studies of sexual orientation and mental health morbidity have enabled researchers to find some elevated risk for stress-sensitive disorders that is generally attributed to the harmful effects of antihomosexual bias. Lesbians and gay men who seek mental health services must find culturally competent care within systems that may not fully address their concerns. The affirmative therapies offer a model for intervention, but their efficacy and effectiveness need to be empirically documented. Although methodological obstacles are substantial, failure to consider research questions in this domain overlooks the welfare of individuals who may represent a sizable minority of those accessing mental health services annually.

Rifampicin for ulcerative colitis

The public health approach to injury control is now widely accepted. Since the development of this approach, there has been a shift in the perspective of public health programs to include broader definitions of health. There have also been increasing efforts to evaluate public health interventions in terms of health outcomes at the population level. In this context, it might be appropriate to broaden the focus of injury prevention to target more specifically injuries that are not life-threatening. Although they are not responsible for major morbidity at an individual level, they probably account for the greatest decrement in the health of the population as a whole.
