RÉSUMÉ
Physical activity (PA) is healthy for People Living with HIV and AIDS (PLWHA). This study examined the PA profile of 978 PLWHA based on PA domains and PA intensity. The study also sought to determine whether employment status and level of education can predict PA among PLWHA of low SES. PA and sociodemographic data of 978 PLWHA of mean age 35 (8.77) years were collected using the global physical activity questionnaire and a sociodemographic questionnaire. Results showed that, participants engaged more in work-related PA [160.11 (346.95) min/wk], followed by transport related PA [115.21(SD = 142.04) min/wk], and lastly in leisure related PA [40.84 (SD = 110.37) min/wk]. Participants also engaged more in moderate PA [265.86 (SD = 335.45) min/wk], than in vigorous PA [50.29 (SD = 205.30) min/wk]. Employment was a significant predictor of overall PA controlling for age, CD4 count and education level. The model explained 2.5% of the variance (R2 = 0.025) on overall PA and tested significant at a 0.01 alpha level (p < 0.01). PA interventions for this population should be domain- and intensity-specific. Researchers promoting healthy lifestyle behaviour change can benefit from determining the factors that facilitate domain-specific PA.

AIM: Aim of the present study was to determine whether the association between obesity and physical fitness in children and adolescents is age- and sex-specific. METHODS: A total of 4519 children and adolescents aged 4-17 years grouped by age (4-5, 6-10, 11-13 and 14-17 years), sex and BMI (normal-weight: BMI≤90th percentile; overweight: BMI>90th percentile; adipose: BMI>97th percentile) participated in this large-scale representative cross-sectional study. Endurance, strength, flexibility and fine and gross motor coordination was measured using the following physical fitness tests: PWC170, push-ups test, standing long-jumps, side-to-side jumps, one-minute single leg stance on the dominant leg, balancing backwards on three beams of different width, lowest point reached by the fingertips while standing on a box with legs extended, reaction to colour changes of traffic light, tracing lines without touching the rim and sorting 25 pens. RESULTS: Overweight and obese boys and girls had lower physical fitness values describing endurance, strength and gross motor coordination than normal-weight boys and girls, respectively (P<0.001 for all; boys: -12% and -19%, respectively; girls: -9% and -19%, respectively). Differences in physical fitness between weight groups were greater in older groups (P<0.001). Fine motor skills and flexibility values did not differ between weight groups. CONCLUSION: The disparity in physical fitness, in particular in endurance, strength and gross motor coordination, between obese and normalweight is greater in adolescents than in children. Physical fitness programs are warranted for all overweight and obese children and adolescents but especially for overweight and obese adolescents.

The question of whether physical activity is associated with positive aspects of health becomes increasingly more important in the light of the health status in today's children and adolescents and due to the changing lifestyle with respect to everyday activity. The German Health Interview and Examination Survey for Children and Adolescents (KiGGS) collected the first set of nationwide representative cross-sectional data to examine the relationship between health and physical activity. Taking sociodemographic parameters into consideration, the results suggest a positive association between self-estimated general health and several types of physical activity. The results vary with respect to gender and type of physical activity. For methodological reasons, causal conclusions can only be drawn after longitudinal data of the second wave of KiGGS are available.

This article deals with the question of which longitudinal effect physical activity at the adult age can have on physical fitness and on people's subjective as well as objective state of health. Are persons who are regularly and continuously physically active healthier and fitter than people beginning physical activity at a later age, or than those who have never been physically active at all? The results of the presented longitudinal study, run over a time range of 10 years, with subjects at the middle and later adult age, show that on average physical fitness and subjective health decline with in the analysed time range, but positive effects of physical activity do exist. These show up in a decelerated decline. The constant sportsmen benefit most here, but also a late start with physical activity can improve and stabilize physical fitness and health. Anyway, former physical activity is no guarantee for lifelong fitness and health. The group of the dropouts registers large degradations in both variables after quitting physical activity.
