The effects of a 2-year physical education program (SPARK) on physical activity and fitness in elementary school students. Sports, Play and Active Recreation for Kids.

OBJECTIVES This study evaluated a health-related physical education program for fourth- and fifth-grade students designed to increase physical activity during physical education classes and outside of school. METHODS Seven schools were assigned to three conditions in a quasi-experimental design. Health-related physical education was taught by physical education specialists or trained classroom teachers. Students from these classes were compared with those in control classes. Analyses were conducted on 955 students with complete data. RESULTS Students spent more minutes per week being physically active in specialist-led (40 min) and teacher-led (33 min) physical education classes than in control classes (18 min; P < .001). After 2 years, girls in the specialist-led condition were superior to girls in the control condition on abdominal strength and endurance (P < .001) and cardiorespiratory endurance (P < .001). There were no effects on physical activity outside of school. CONCLUSIONS A health-related physical education curriculum can provide students with substantially more physical activity during physical education classes. Improved physical education classes can potentially benefit 97% of elementary school students.

Comorbidity of substance use disorders with mood and anxiety disorders: Results of the international consortium in psychiatric epidemiology

This article reports the results of a cross-national investigation of patterns of comorbidity between substance use and psychiatric disorders in six studies participating in the International Consortium in Psychiatric Epidemiology. In general, there was a strong association between mood and anxiety disorders as well as conduct and antisocial personality disorder with substance disorders at all sites. The results also suggest that there is a continuum in the magnitude of comorbidity as a function of the spectrum of substance use category (use, problems, dependence), as well as a direct relationship between the number of comorbid disorders and increasing levels of severity of substance use disorders (which was particularly pronounced for drugs). Finally, whereas there was no specific temporal pattern of onset for mood disorders in relation to substance disorders, the onset of anxiety disorders was more likely to precede that of substance disorders in all countries. These results illustrate the contribution of cross-national data to understanding the patterns and risk factors for psychopathology and substance use disorders.

Perceived discrimination and depression among Mexican-origin adults in California

We contend that perceived discrimination has an independent effect on depression outcomes among adults of Mexican origin. Using a sample of 3,012 Mexican-origin respondents in Fresno, California in 1995/96 (ages 18-59) we investigate the direct and moderating connections between perceived discrimination, acculturative stress, and mental health (CES-D). We also investigate the social patterning of perceived discrimination. While more highly acculturated immigrant respondents were more likely to experience discrimination than their less acculturated counterparts, more highly acculturated U.S. born respondents were less likely to experience discrimination. Discrimination was directly related to depression, but this effect was moderated through nativity/country of residence, English-language acculturation, sex, and country of education variables. Moderate levels of legal status acculturative stress were especially depressive for native-born U.S. residents.

Effects of social support from various sources on depression in elderly persons

Although global measures of social support demonstrate significant effects on psychological and physical well-being, the differential significance of various support sources is largely unknown. The present study examines differences in the effects of functional expressive support by source on depressive symptoms. This approach is contrasted with network interaction studies of elderly persons, which do not measure functional support but do suggest that friends are distinctly significant. Spouse, friends, and adult children were found to rank in descending order of importance; relatives show no effect. Low support may have stronger effects than unavailability of sources. Effects of supports and stressors are not conditioned by age, sex, or widowhood. Implications of findings and further research needs are discussed.

Lifetime prevalence of and risk factors for psychiatric disorders among Mexican migrant farmworkers in California.

OBJECTIVES In this study, the prevalence of and risk factors for 12 psychiatric disorders were examined by sex and ethnicity (Indian vs non-Indian) among Mexican migrant farm-workers working in Fresno County, California. METHODS Subjects aged 18 through 59 years were selected under a cluster sampling design (n = 1001). A modified version of the Composite International Diagnostic Interview was used for case ascertainment. The effects of sociodemographic and acculturation factors on lifetime psychiatric disorders were tested. RESULTS Lifetime rates of any psychiatric disorder were as follows: men, 26.7% (SE = 1.9); women, 16.8% (SE = 1.7); Indians, 26.0% (SE = 4.5); non-Indians, 20.1% (SE = 1.3). Total lifetime rates were as follows: affective disorders, 5.7%; anxiety disorders, 12.5%; any substance abuse or dependence, 8.7%; antisocial personality, 0.2%. Lifetime prevalence of any psychiatric disorder was lower for migrants than for Mexican Americans and for the US population as a whole. High acculturation and primary US residence increased the likelihood of lifetime psychiatric disorders. CONCLUSIONS The results underscore the risk posed by cultural adjustment problems, the potential for progressive deterioration of this populations mental health, and the need for culturally appropriate mental health services.

Long-Term Effects of a Physical Education Curriculum and Staff Development Program: SPARK

This 4-year study, conducted in seven elementary schools assigned to three conditions--Physical Education Specialists (PES), Trained Classroom Teachers (TT), and Controls (CO)--had two parts. The first investigated effects of a health-related physical education program on quantity and quality of lessons. Specialists produced the best outcomes, and TT were significantly better than nontrained peers. Part Two assessed maintenance effects approximately 1.5 years after intervention termination. Withdrawal of specialists significantly reduced the quantity and quality of physical education. TT maintained PES frequency but with a loss in lesson quality and a decline in student activity to 88% of intervention levels. Results support employing specialists and demonstrate the need for extensive professional development for classroom teachers responsible for physical education.

The Development of Self-Administered Physical Activity Surveys for 4th Grade Students

This study evaluates the test-retest reliability and validity of self-report measures of physical activity that can be self-administered in classroom settings to 4th grade students. Four different self-report formats were tested on 66 students. To assess test-retest reliabilities, self-report measures were administered on two occasions, separated by a 3-day interval between Time 1 (Friday) and Time 2 (Monday). One-way model intraclass reliabilities ranged from .51 to .74. Three days of monitoring with the Caltrac accelerometer were used as the validity criterion. Only one of the three weekly recalls, the Weekly Activity Checklist, was supported by significant validity correlations at both Time 1 (r = .34, p < .01) and Time 2 (r = .26, p < .05). The 1-day recall, Yesterday Activity Checklist, correlated significantly (r = .33, p < .01) with the previous days Caltrac monitor score. Although two of the physical activity recall formats were found to be superior to two others, these data highlight the limitations of childrens self-reports. Two self-report formats were found to have modest levels of reliability and validity with 4th grade children when administered in a classroom setting.

12-month prevalence of DSM-III-R psychiatric disorders among Mexican Americans: Nativity, social assimilation, and age determinants.

The burden of disease attributable to mental illnesses has major costs and human services implications in the United States. Mexican Americans compose two thirds of the nations largest and fastest-growing minority group, Latinos. We report 12-month DSM-III-R psychiatric disorder rates among Mexican Americans derived from a population survey of immigrants and US-born adults of Mexican origin conducted in rural and urban areas of central California. Rates of 12-month total mood, anxiety, and substance disorders were 14.2% for immigrant women, 12.6% for immigrant men, 27.8% for US-born women, and 27.2% for US-born men. For immigrants, younger age of entry and longer residence in the United States were associated with increased rates of psychiatric disorders. Three dominant explanations are reviewed to explain these differences: selection, social assimilation and stress, and measurement artifact. Our results and other research studies collectively support a social assimilation explanation based on aversive impact on health behaviors and protective resources such as families. Greater social assimilation increases psychiatric morbidity, with rates for subjects who are US-born of Mexican origin approximately the same as rates for the US general population.

Depressive symptoms and their correlates among immigrant Mexican women in the United States

Correlates of depressive symptomatology and caseness are examined for a survey sample of N = 1825 poor Mexican immigrant women in San Diego County, California. The Center for Epidemiologic Studies--Depression (CES--D) checklist is tested against a variety of demographic variables as well as health status and service utilization rates. Statistically significant associations were found between CES--D and education, years in the United States, income, marital status and number of adults in household. Also significant were associations with health status, confidant support and recent, traumatic life event. Utilization rates point to medical doctors as the major source of formal treatment and a heavy reliance on family and friends. The implications of the high disorder rates for diagnosis and treatment among immigrants are discussed.
