Epidemiology, physical examination, and neurodiagnostics

The overall frequency of troublesome neck pain is estimated to be approximately 34%, and it was observed that the frequency of complaints lasting 1 month or longer was higher in women than in men. The prevalence increased with age with regard to both pain duration and chronic pain. A total of approximately 14% of a randomly selected population meets the criteria for chronic neck pain, with complaints lasting for more than 6 months. It could be that the structural transformation of the intervertebral disc, the uncovertebral processes, and the zygapophyseal joints is a process accompanied by disturbed function, ultimately inducing pain. For diagnosis of radicular and myelopathic syndromes, the physical and neurologic examination is enhanced by neurophysiologic assessment. Electromyography, performed with needle electrodes, is the oldest method to diagnose nerve root compression syndromes and is claimed to have no false positive results. Electromyography for radiculopathy is justified if clinical symptoms, such as muscular weakness, don't correlate with clinical findings (diminished or absent reflex), or for documentation of muscle activity if difficult decompressive surgery is expected. For diagnosis of cervical myelopathy by routine examination, the sensory evoked potentials by stimulation of tibial nerve as well as motor evoked potentials from upper and lower extremities are recommended because clinically "silent" myelopathy can be verified by abnormalities in evoked potentials. During history taking, the symptoms possibly attributed to radiculopathy or myelopathy should be differentiated from primary systemic neurologic disorders such as shoulder angiotrophy ("plexus neuritis"), multiple sclerosis, amyotrophic laterals sclerosis, and peripheral neuropathy. The assessment of range of motion, the functional status of shoulder and neck muscles, and palpatory examination of soft tissue is widely used to determine non-operative therapeutic procedures. However, scientifically, the validity of the different testing procedures has not been evaluated satisfactorily.     

Effects of obesity, social interactions, and physical environment on physical activity in preschoolers.

Examined demographic, environmental, and parent–child interactional correlates of physical activity in 222 preschoolers (aged 3–6 yrs). Results indicate a significant relationship between (1) children's relative weight, parental weight status, and percentage of time spent outdoors, and (2) children's activity levels. Parental obesity was associated with lower levels of physical activity in children. Childhood relative weight was associated with slightly higher levels of physical activity, and more outdoor activity was associated with higher activity levels. Parental participation in children's activities significantly interacted with levels of parental obesity in predicting children's activity levels.

Values, personality, physical characteristics, and refractive error

A questionnaire containing: (a) a questionnaire of physical characteristics associated with psychosomatic symptoms, (b) questions to determine the presence of myopia or hypermetropia but not the amount of error, (c) a shortened version of the Gough Adjective Check List, and (d) the Heist and Yonge Omnibus Personality Inventory were administered to 782 introductory psychology students attending Washington State University. This group consisted of 297 self-identified myopes (117 males, 180 females), 439 emmetropes (207 males, 232 females), and 46 hypermetropes (15 males, 31 females). Results indicated that myopes and nonmyopes differed from one another with respect to their value systems, personality, and physical characteristics as assessed by the components of the questionnaire. Differences in these characteristics were consistently found by all assessment techniques to exist most often between myopes and hypermetropes and between emmetropes and hypermetropes rather than between myopes and emmetropes. In general myopes exhibited a personality pattern of introversion, whereas hypermetropes maintained a pattern described as extroverted.     

Body image, physical attractiveness, and depression.

224 17–63 yr olds completed measures of self-perceived physical attractiveness and depression, and static full-body videotapes of Ss were assessed by objective raters, to investigate the relationship between Ss' body image, rated physical attractiveness, and depression. Measures included the Body-Self Relations Questionnaire, Center for Epidemiologic Studies Depression Scale (CES-D), a body parts satisfaction scale, and a self-labeling depression scale. Ss were classified as depressed (n?=?35) or nondepressed (n?=?42) on the basis of conjunctive criteria of self-labeling and extreme groups on the CES-D. It was hypothesized that (1) depressed Ss would report being less satisfied with their body parts and physical appearance and would regard themselves as less physically attractive than would nondepressed Ss, (2) objective raters would perceive depressed Ss as less physically attractive than nondepressed Ss, and (3) depressed Ss would distort their degree of physical attractiveness and perceive themselves to be less attractive than objective raters regarded them. Results indicate that, as hypothesized, depressed Ss were less satisfied with their bodies and saw themselves as less physically attractive than nondepressed Ss. These groups did not differ with respect to observer-rated physical attractiveness. Support was obtained for A. T. Beck's (1973, 1976) cognitive hypothesis that depressed persons negatively distort their body images; however, results also indicate substantial positive distortion among nondepressed Ss.

Anti-Semitism, distraction and physical aggression.

Examined the aggressive responses of persons who varied in level of anti-Semitism and who were either distracted or not distracted from an insulter. 34 male undergraduates, chosen as Ss through a questionnaire which included the 10-item Anti-Semitism Scale and the 28-item California F Scale, participated in a paired associate learning task in which their performance was demeaned by a tape recorded series of disparaging remarks presumably given by their peer. Following this, critical Ss either relaxed under conditions where voice and movement cues from their insulter were heard, or Ss observed a film designed to distract them from their insulter. The critical Ss were then requested to teach their peer a paired associate list under conditions in which they administered shock to their partner. Results of the 3 * 2 * 3 repeated measures analysis of variance with 3 levels of anti-Semitism, 2 distraction conditions, and 3 trials indicate that distraction reduced the intensity of shock delivered to the peer. Ss tended to rate themselves as less annoyed and less anxious under distraction conditions. Ss varying in anti-Semitism did not differ in the amount of shock delivered to their partner. The situational demands may have been powerful enough to override the effects of personality differences. 2 interpretations are offered for the finding that the highly prejudiced Ss perceived the shock delivered to their peer as more painful than the less prejudiced Ss: (a) the possibility that this difference reflected the highly prejudiced Ss' lower guilt level for aggressing; and (b) the possibility that the highly prejudiced Ss used different mechanisms to reduce the discomfort engendered by harming another person than those used by their less prejudiced peers.

Associations between skeletal muscle properties, physical fitness, physical activity and coronary heart disease risk factors in men

High physical fitness and physical activity are associated with favourable lipid levels, especially a high level of high density lipoprotein cholesterol (HDL-C). A person's skeletal muscle properties, metabolism and percentage of different muscle fibres (ST-%), which may modify coronary heart disease (CHD) risk factors, such as serum insulin, obesity and serum sex hormones may also influence his fitness level and leisure-time physical activity. We studied the associations of physical fitness, physical activity and ST-% with serum lipids and lipoproteins in 72 healthy men. Their parameters were compared with those of 20 men with defined CHD. Significant interrelationships between ST-%, fitness and leisure-time physical activity index (LTPAI) were observed. Multiple regression analysis showed that ST-%, fitness and leisure-time physical activity explained about 32% of the variation in HDL-C in the healthy men. In healthy men ST-% correlated positively with fitness (r(s) = 0.62, P < 0.001) and with LTPAI (r(s) = 0.62, P < 0.001). Fitness level also correlated significantly with LTPAI (r(s) = 0.81, P < 0.001). Serum insulin showed negative associations with ST-% (r(s) = -0.63, P < 0.001) and fitness (r(s) = -0.54, P < 0.001) and LTPAI (r(s) = -0.62, P < 0.001). Free fraction of testosterone correlated negatively with serum HDL-C level (r(s) = -0.34, P < 0.01), with fitness (r(s) = -0.41, P < 0.001) and with LTPAI (r(s) = -0.54, P < 0.001). In sedentary men with the lowest fitness and physical activity the mean of ST-% (45%) was similar to that in CHD patients (44%). However, ST-% in men in the highest tertile of physical activity and fitness (68%) was significantly higher than in CHD patients and in men in the lowest tertile of physical activity and fitness. Skeletal muscle enzyme activity in lipid metabolism was significantly lower in both CHD patients and in sedentary and low-fit men than that in fitter and physically active men. The present data imply that skeletal muscle properties are important determinants of risk profiles, such as physical activity, fitness and serum lipid and lipoprotein patterns. Although fitness is a graded, independent predictor of mortality from CHD, a relatively high fitness level is not enough. This was clearly observed in the clustering analysis, in which the healthy men, according to their ST-%, fitness, leisure-time physical activity and serum sex hormone binding globulin (SHBG), fell into three natural groups: (i) Inactive men with lowest ST-% (mean 42%), lowest fitness (10.7 METs) and lowest HDL-C (1.36 mm/l); (ii) Fit men with high ST-% (66%), high fitness (14.5 METs) and moderately high HDL-C (1.54 mol/l); (iii) Active men with high ST-% (66%), highest fitness (14.9 METs) and highest serum HDL (1.83 mmol/l). The results support the idea that both fitness and physical activity give further protection against CHD by modifying risk factors. Our findings also suggest that skeletal muscle properties should be considered in the studies which assess CHD risk factors and their modifications especially in the field of health-related fitness.     

Interaction between physical environment, social environment, and child characteristics in determining physical activity at child care.

Objective: To investigate the association between the child-care environment and physical activity of 2- and 3-year-olds. Based on an ecological view of environmental influences on health behavior, we hypothesized that the social and physical environment, as well as child characteristics (age and gender), would show independent and interactive effects on children's physical activity intensity. Design: Observations of physical activity intensity were performed among children (N = 175) at 9 Dutch child-care centers. Aspects of the child-care environment were assessed using the validated Environment and Policy Assessment and Observation (EPAO) Instrument. Multilevel linear regression analyses examined the association of environment and child characteristics with children's activity intensity. Moderation was tested by including interaction terms in the analyses, with subsequent post hoc analyses for significant interaction terms. Main Outcome Measure: Observed child physical activity intensity, measured with the Observational System for Recording Physical Activity in Children—Preschool Version. Results: A large proportion of the observed activities were classified as sedentary, while far fewer observations were classified as moderate or vigorous. Activity opportunities in the physical environment (assessed using EPAO) and prompts by staff and peers were significantly and positively related to physical activity intensity, while group size was negatively related to activity intensity. The influence of the physical environment was moderated by social environment (peer group size), while the social environment in turn interacted with child characteristics (age and gender) in determining activity intensity. Conclusion: Our findings are in line with the ecological perspective regarding environmental influences on behavior, and stress the importance of incorporating the child-care environment in efforts to prevent childhood overweight and obesity.

Mental rotation, physical rotation, and surface media.

Ss made mirror-normal discriminations on alphanumeric characters shown in different orientations in the picture plane. Either the characters or the background rotated during stimulus presentation in Exps 1–3. Character rotation in the direction of mental rotation facilitated mental rotation, whereas rotation in the opposite direction inhibited it. In Exp 4, characters were presented in different surface media so as to stimulate only 1 representation at a time. Mental rotation performance was similar whether the stimuli were defined by luminance, color, texture, relative motion, or binocular disparity, suggesting that mental rotation occurs at a level beyond that of the independent analyses of these different media. These results support those of Exps 1–3 in excluding the participation of low-level motion analysis centers in the mental rotation processes.

Nutrition, physical activity, and bone health in women

Calcium and vitamin D can significantly impact bone mineral and fracture risk in women. Unfortunately, calcium intakes in women are low and many elderly have poor vitamin D status. Supplementation with calcium (approximately 1000 mg) can reduce bone loss in premenopausal and late postmenopausal women, especially at sites that have a high cortical bone composition. Vitamin D supplementation slows bone loss and reduces fracture rates in late postmenopausal women. While an excess of nutrients such as sodium and protein potentially affect bone mineral through increased calcium excretion, phytoestrogens in soy foods may attenuate bone loss through estrogenlike activity. Weight-bearing physical activity may reduce the risk of osteoporosis in women by augmenting bone mineral during the early adult years and reducing the loss of bone following menopause. High-load activities, such as resistance training, appear to provide the best stimulus for enhancing bone mineral; however, repetitive activities, such as walking, may have a positive impact on bone mineral when performed at higher intensities. Irrespective of changes in bone mineral, physical activities that improve muscular strength, endurance, and balance may reduce fracture risk by reducing the risk of falling. The combined effect of physical activity and calcium supplementation on bone mineral needs further investigation.     

Newborn dopamine-beta-hydroxylase, minor physical anomalies, and infant temperament

The authors examined newborn anomaly scores for 193 normal infants in relation to obstetrical history, newborn dopamine-beta-hydroxylase (DBH), and 5-month (N=185) and 1-year (N=123) infant behavior, determined by a questionnaire completed by their mothers. There was no significant relationship between anomaly score and obstetrical history or 5-month infant temperament; low significant correlations were found between newborn DBH and 1) infant irritability and unsociable response and 2) 1-year anomaly scores and reported activity levels. The authors discuss the possible importance of these findings.     

Men, family-role quality, job-role quality, and physical health.

[Correction Notice: An erratum for this article was reported in Vol 12(2) of Health Psychology (see record 2008-10479-001). In this article the title for Table 1 (p. 50) should be "Correlations Between Rewards and Concerns in the Job, Marital, and Parent Roles." Also, the last item in the first column of the table should read "6. Parent-role concerns."] The relationship between the quality of men's family roles, as spouse and as parent, and the quality of men's job role, on the one hand, and their reports of physical symptoms, on the other, was examined in men drawn from a random sample of 300 dual-earner couples. The main effect of marital-role quality (i.e., rewards and concerns) on physical health was estimated, as was the Marital-Role Quality&×&Job-Role Quality interaction effect. With respect to the present role, the effect of both parent-role occupancy and parent-role quality was estimated. After controlling for job-role quality, it was found that parent-role occupancy had neither main nor interactive effects. However, among the men who occupied all 3 roles (n&=&180), only parent-role concerns were a significant predictor of physical health reports. Thus, concerns in the parent role are a major unmeasured source of variance in studies of the stress–illness relationship in men.

Athletic classmates, physical self-concept, and free-time physical activity: A longitudinal study of frame of reference effects.

The systematic analysis of factors that promote or impede physical activity in children is an urgent task for educational researchers. The present study investigated the reciprocal relationship between physical self-concept, teacher-assigned grades in physical education classes, and free-time physical activity, and analyzed positive and negative consequences of being in a class with high class-average physical ability. Data from a large, representative sample of 1,095 preadolescents from 66 classrooms were examined within a longitudinal framework. Multilevel analyses showed that membership in a class with high class-average physical ability was associated with lower physical self-concept and free-time physical activity and highlighted the significant role of teacher-assigned grades in the development of physical self-concept and physical activity. Furthermore, as predicted, there were positive reciprocal effects between physical self-concept and physical activity levels. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Marital psychological and physical aggression and children's mental and physical health: Direct, mediated, and moderated effects.

Relations between marital aggression (psychological and physical) and children's health were examined. Children's emotional insecurity was assessed as a mediator of these relations, with distinctions made between marital aggression against mothers and fathers and ethnicity (African American or European American), socioeconomic status, and child gender examined as moderators of effects. Participants were 251 community-recruited families, with multiple reporters of each construct. Aggression against either parent yielded similar effects for children. Children's emotional insecurity mediated the relation between marital aggression and children's internalizing, externalizing, and posttraumatic stress disorder symptoms. No differences were found in these pathways for African American and European American families or as a function of socioeconomic status or child gender.

Relationship of childhood sexual, physical, and combined sexual and physical abuse to adult victimization and posttraumatic stress disorder

OBJECTIVE: Prior research has suggested that women who experience childhood sexual abuse are at increased risk for sexual victimization and Posttraumatic Stress Disorder (PTSD) in adulthood. However, previous studies have paid insufficient attention to the overlap of childhood sexual and physical abuse. In the present study we disentangled the separate and combined effects of childhood sexual and physical abuse by comparing groups of participants who reported contact childhood sexual abuse only (SA), sequelae of childhood physical abuse only (PA), combined childhood sexual and physical abuse (CA), or no child abuse (NA). METHOD: A sample of 475 female college students completed measures of sexual and physical abuse in childhood (before age 15) and adulthood (after age 15), PTSD and trauma symptoms, and demographic variables. Of these participants, 27 were assigned to the SA group, 53 to the PA group, 31 to the CA group, and 211 to the NA group. RESULTS: The highest rate of adult sexual and/or physical victimization was reported by the CA group, followed by the PA group, with lower rates reported by the SA and NA groups. Using adult victimization as a covariate, the analyses revealed that the CA group reported significantly higher rates of PTSD and trauma symptoms compared to the NA group. CONCLUSIONS: The results suggest that prior reports of differences in rates of adult victimization and PTSD between women who experienced childhood sexual abuse and women who did not may be attributable to the inclusion of participants with a history of combined childhood sexual and physical abuse in childhood sexual abuse groups. The importance of separating physical and combined forms of victimization from sexual abuse is discussed.     

Pain, depression, and physical functioning following burn injury.

Objective: Little is known about how pain and depression after burn injury may influence long-term outcomes such as physical functioning. This prospective study examined associations between pain, depression, and physical functioning in a sample of burn injury survivors. Design and Participants: Questionnaires assessing pain, depression, and physical functioning were completed by 64 (52% of original sample) adult burn survivors shortly after discharge from burn care and at 1- and 2-year follow-ups. Results: Pain and physical functioning improved over the 2 years of the study, whereas depression levels were stable. Pain and depression were associated with poorer physical functioning over time, but associations varied according to the time span under consideration. Also, the association between pain and physical functioning was strongest among persons with higher depression scores. Conclusions: Pain and depression may contribute independently to compromises in physical functioning. The co-occurrence of pain and depression represents even greater risk for reduced physical functioning over time among burn survivors.

Sociability: Personality, social context, and physical setting.

Sociability, measured as amount of participation in a peer-group conversation, was examined as a function of traits (Personality Research Form), social context, and physical setting. Same-sex quartets of 84 13–17 yr old students discussed a topic selected by an outsider and a topic of the group's own choice. Amount of participation was expected to vary with personality (affiliation, defendence, and dominance), social context (level of acquaintance and friendship in the group), physical setting (seating arrangement), and interactions among these. Ss' participation rate was significantly related to affiliation, level of friendship, a person?×?setting interaction (seating arrangement?×?defendence) and a person?×?person interaction (affiliation?×?defendence). These relationships are discussed as they relate to a model of sociability and as they bear on the person?×?situation issue. Results demonstrate that sociability is a function of dispositions brought to a setting by an individual, the social context of that setting, and the physical arrangement of the setting.

Heterosexual social competence, anxiety, avoidance and self-judged physical attractiveness

The relationship between self-judged physical attractiveness and opposite-sex behavior was examined as part of a large survey on the interaction patterns of 963 college students. The findings suggest that a self-rated negative physical image is related to significantly high levels of heterosexual difficulties.     

Physical attractiveness, physical effectiveness, and self-concept in late adolescents

The differential role of various body attitudes in predicting the self-concepts of late adolescents (124 males and 218 females), enrolled in introductory psychology courses, was assessed. Subjects rated 24 body characteristics in terms of 1) how physically attractive they assumed these parts of their bodies were, and 2) how physically effective they assumed them to be; subjects also responded to a short self-concept scale. In accordance with the theory of Erikson (1968) and of McCandless (1970), it was expected that attractiveness attitudes should contribute more to the self-concepts of females than should effectiveness attitudes, while a reverse pattern of interrelatedness was expected for males. Results indicated a higher correspondence between what are seen as attractive body parts and what are viewed as effective body components for males than for females. Moreover, findings from step-wise multiple regression analyses of each sex group's ratings of the body parts for attractiveness and effectiveness, respectively, each with the criterion variable constituting mean self-concept score, were consistent with expectations. For females, the multiple correlation between attractiveness ratings and self-concept was greater than the multiple correlation between effectiveness ratings and self-concept, and more attractiveness variables than effectiveness variables were significant predictors of self-concept. The converse of these findings were obtained with the males' data. The relevance of these results for theories of personality development were discussed.     

Parent-child physical play with rejected, neglected, and popular boys.

This study compares the parent–child interactions of rejected, neglected, and popular boys in a paradigm emphasizing physical play. Twelve boys, 3 to 5 years of age, of each sociometric category were recruited from nursery schools and observed in interactions with their parents at home. It was found that the fathers of neglected boys engaged in less affectively arousing, physical play than the fathers of popular and rejected boys. In addition, there was more overstimulation and avoidance of stimulation among the rejected boys compared with the popular boys. The results indicate the importance of the regulation of affect for social competence and illustrate strong links between the parent and peer social systems.
