RESUMO
OBJECTIVE: To assess the proportion of severe maternal outcomes resulting from indirect causes, and to determine pregnancy outcomes of women with indirect causes. DESIGN: Secondary analysis of the WHO Multicountry Survey on Maternal and Newborn Health. SETTING: A total of 359 health facilities in 29 countries in Africa, Asia, Latin America, and the Middle East. SAMPLE: A total of 314 623 pregnant women admitted to the participating facilities. METHODS: We identified the percentage of women with severe maternal outcomes arising from indirect causes. We evaluated the risk of severe maternal and perinatal outcomes in women with, versus without, underlying indirect causes, using adjusted odds ratios and 95% confidence intervals, by a multilevel, multivariate logistic regression model, accounting for clustering effects within countries and health facilities. MAIN OUTCOME MEASURES: Severe maternal outcomes and preterm birth, fetal mortality, early neonatal mortality, perinatal mortality, low birthweight, and neonatal intensive care unit admission. RESULTS: Amongst 314 623 included women, 2822 were reported to suffer from severe maternal outcomes, out of which 20.9% (589/2822; 95% CI 20.1-21.6%) were associated with indirect causes. The most common indirect cause was anaemia (50%). Women with underlying indirect causes showed significantly higher risk of obstetric complications (adjusted odds ratio, aOR, 7.0; 95% CI 6.6-7.4), severe maternal outcomes (aOR 27.9; 95% CI 24.7-31.6), and perinatal mortality (aOR 3.8; 95% CI 3.5-4.1). CONCLUSIONS: Indirect causes were responsible for about one-fifth of severe maternal outcomes. Women with underlying indirect causes had significantly increased risks of severe maternal and perinatal outcomes.

OBJECTIVE: To assess the association between advanced maternal age (AMA) and adverse pregnancy outcomes. DESIGN: Secondary analysis of the facility-based, cross-sectional data of the WHO Multicountry Survey on Maternal and Newborn Health. SETTINGS: A total of 359 health facilities in 29 countries in Africa, Asia, Latin America, and the Middle East. SAMPLE: A total of 308 149 singleton pregnant women admitted to the participating health facilities. METHODS: We estimated the prevalence of pregnant women with advanced age (35 years or older). We calculated adjusted odds ratios of individual severe maternal and perinatal outcomes in these women, compared with women aged 20-34 years, using a multilevel, multivariate logistic regression model, accounting for clustering effects within countries and health facilities. The confounding factors included facility and individual characteristics, as well as country (classified by maternal mortality ratio level). MAIN OUTCOME MEASURES: Severe maternal adverse outcomes, including maternal near miss (MNM), maternal death (MD), and severe maternal outcome (SMO), and perinatal outcomes, including preterm birth (<37 weeks of gestation), stillbirths, early neonatal mortality, perinatal mortality, low birthweight (<2500 g), and neonatal intensive care unit (NICU) admission. RESULTS: The prevalence of pregnant women with AMA was 12.3% (37 787/308 149). Advanced maternal age significantly increased the risk of maternal adverse outcomes, including MNM, MD, and SMO, as well as the risk of stillbirths and perinatal mortalities. CONCLUSIONS: Advanced maternal age predisposes women to adverse pregnancy outcomes. The findings of this study would facilitate antenatal counselling and management of women in this age category.

BACKGROUND: Secondhand smoke (SHS) exposure cause of morbidity and mortality, especially in non-smokers and children. This study tested the effectiveness of an intervention for reducing exposure to SHS in homes by creating smoke-free environment where 1 to 5-year old infants reside.METHODS: A cluster randomised controlled trial was conducted in a rural geographic area of Thailand, with 47 villages assigned to either an intervention or a comparison group. The intervention consisted of self-education and infographic material, together with 45 text messages delivered via short message service. The control group received the self-education after the intervention at 3 months. The primary outcome was assessed by parent´s self-reported in exposure to SHS in home. Multiple logistic regression was used to test the effect of the intervention.RESULTS: The effects of the intervention increased the likelihood of a reducing exposure to SHS at home by 1.8-fold (95%CI 1.04 to 3.11). The average number of days of SHS exposure at home (7 days) also decreased by -1.25-fold (95%CI -1.85 to -0.66) in the intervention group.CONCLUSION: The effectiveness of the intervention in reducing SHS exposure at home by a creating a smoke-free environment was observed to be statistically significant.
