OBJECTIVE: To assess the association of physical activity, television program viewing and other forms of video viewing with the prevalence of obesity among school children. DESIGN: Cross-sectional study. SUBJECTS: 712 children, 9 ± 16 y old, from a low-and a middle-income town in the Mexico City area. MEASUREMENTS: Children completed a self administered questionnaire to assess time spent in physical activity and television viewing, and diet. Height weight and triceps skinfolds were measured. The outcome variable was obesity, and the covariates were hours of television programs and other video viewing, physical activity, energy intake, percentage of energy from fat, town of location of school, age, gender and perception of mother's weight status. RESULTS: Among 461 children with complete information, 24% were classi®ed as obese. Children reported an average of 4.1 AE 2.2 had watching television (2.4 AE 1.5 had for TV programs and 1.7 AE 1.5 had for video cassette recorder (VCR) or videogames), and 1.8 AE 1.3 had in moderate and vigorous physical activities. Odds ratios (OR) of obesity were 12% higher for each hour of television program viewing per day (OR 1.12, 95% con®dence interval (CI) 1.02, ± 1.22), and 10% lower for each hour of moderateavigorous physical activity per day (OR 0.90, 95% CI 0.83 ± 0:98), controlling for age, gender, town and perception of mother's weight status. Children in the middle-income town had higher adjusted odds of obesity (OR 2.58, 95% CI 1.47 ± 4.54). CONCLUSION: Physical activity and television viewing, but not VCRavideogames use, were related to obesity prevalence in Mexican children 9 ± 16 y old.

Objective We aimed to determine the prevalence and risks of late fetal deaths (LFDs) and early neonatal deaths (ENDs) in women with medical and obstetric complications.Design Secondary analysis of the WHO Multicountry Survey on Maternal and Newborn Health (WHOMCS).Setting A total of 359 participating facilities in 29 countries.Population A total of 308 392 singleton deliveries.Methods We reported on perinatal indicators and determined risks of perinatal death in the presence of severe maternal complications (haemorrhagic, infectious, and hypertensive disorders, and other medical conditions).Main outcome measures Fresh and macerated LFDs (defined as stillbirths ≥ 1000 g and/or ≥28 weeks of gestation) and ENDs.Results The LFD rate was 17.7 per 1000 births; 64.8% were fresh stillbirths. The END rate was 8.4 per 1000 liveborns; 67.1% occurred by day 3 of life. Maternal complications were present in 85.6, 86.5, and 88.6% of macerated LFDs, fresh LFDs, and ENDs, respectively. The risks of all three perinatal mortality outcomes were significantly increased with placental abruption, ruptured uterus, systemic infections/sepsis, pre-eclampsia, eclampsia, and severe anaemia.Conclusions Preventing intrapartum-related perinatal deaths requires a comprehensive approach to quality intrapartum care, beyond the provision of caesarean section. Early identification and management of women with complications could improve maternal and perinatal outcomes.
