Individual Participant Data (IPD) Meta-analyses of Randomised Controlled Trials: Guidance on Their Use
by Tierney et alSystematic reviews involving the central collection and analysis of individual participant data (IPD) usually are larger-scale, international, collaborative projects that can bring about substantial improvements to the quantity and quality of data, give greater scope in the analyses, and provide more detailed and robust results. Following this step-by-step guide will help reviewers and users of IPD meta-analyses to understand them better and recognise those that are well designed and conducted and so help ensure that policy, practice, and research are informed by robust evidence about the effects of interventions.
Economic interventions are increasingly recognised as a mechanism to address perinatal health outcomes among disadvantaged groups. In the US, the earned income tax credit (EITC) is the largest poverty alleviation programme. Little is known about its effects on perinatal health among recipients and their children. The authors exploit quasi-random variation in the size of EITC payments to examine the effects of income on perinatal health. Findings suggest that EITC payment size is associated with better levels of several indicators of perinatal health. Instrumental variables analysis, however, does not reveal a causal association between household income and these health measures.
The SWAT and SWAR programme is identifying issues about the methods of trials and systematic reviews about which there is sufficient uncertainty to justify research to support well-informed decision making about future designs and choices.
Using parasite population genetics to understand transmission dynamics in NTDs
by The Editorial TeamSchistosomiasis, is a chronic, debilitating disease. Uganda began a National Control Programme in 2003 with annual MDA of praziquantel. MDA on this scale provides strong selective pressures on the parasite population with an associated risk of drug resistance developing.
Women and Health: the key for sustainable development
by Langer A et alGirls' and women's health is in transition and, although some aspects of it have improved substantially in the past few decades, there are still important unmet needs. Population ageing and transformations in the social determinants of health have increased the coexistence of disease burdens related to reproductive health, nutrition, and infections, and the emerging epidemic of chronic and non-communicable diseases (NCDs). Simultaneously, worldwide priorities in women's health have themselves been changing from a narrow focus on maternal and child health to the broader framework of sexual and reproductive health and to the encompassing concept of women's health, which is founded on a life-course approach.

What is the optimal rate of caesarean section at population level? A systematic review of ecologic studies
by Betran et alThe authors conducted a systematic review to identify, critically appraise and synthesize the analyses of the ecologic association between CS rates and maternal, neonatal and infant outcomes. The findings suggest that at CS rates below this threshold, socio-economic development may be driving the ecologic association between CS rates and mortality. On the other hand, at rates higher than this threshold, there is no association between CS and mortality outcomes regardless of adjustment. The ecological association between CS rates and relevant morbidity outcomes needs to be evaluated before drawing more definite conclusions at population level.
The study aimes to assess both child and adult outcomes in five LMICs. Children of young mothers in LMICs are disadvantaged at birth and in childhood nutrition and schooling. Efforts to prevent early childbearing should be strengthened. After adjustment for confounders, children of older mothers have advantages in nutritional status and schooling. Extremes of maternal age could be associated with disturbed off spring glucose metabolism.
The Early Childhood Obesity Prevention Program (ECHO): an ecologically-based intervention delivered by home visitors for newborns and their mothers
by Cloutier et alThe goals of the Early Childhood Obesity Prevention Program (ECHO) are to examine the 12-month efficacy of a primary obesity prevention program targeting the first year of life that is delivered by home visitors and that engages mothers as agents of change to modify their own behavior and their infant’s behavior through education and skill-building around nutrition, physical activity, and wellness, and then “echoes” her training with linkages to neighborhood programs and resources. ECHO will provide important information about whether an enhanced behavior change curriculum integrated into an existing home visitation program, focused on the mother as the agent of change and linked to neighborhood resources is effective in changing energy balance behaviors in the infant and in the mother. If effective, the intervention could be widely disseminated to prevent obesity in young children.
Does the type of abortion provider influence contraceptive uptake after abortion? An analysis of longitudinal data from 64 health facilities in Ghana
by Maxwell et alThe objectives of this study were to estimate the relationship between the type of abortion provider (consultant physician, house officer, or midwife) and two separate outcomes: (1) the likelihood of adopting postabortion contraception; (2) postabortion contraceptors’ likelihood of receiving a long-acting and permanent versus a short-acting contraceptive method.
The objective of this study was to examine associations between a range of objectively measured and questionnaire-based SB indicators with obesity and body mass index (BMI) to assess whether these associations were independent of physical activity. TV time (but not non-TV sitting or objectively-measured SB) was consistently associated with higher levels of obesity and BMI SD score, even after adjusting for MVPA and other potential confounders. Weaker associations were observed for total sitting time.
In June 2015, FHI 360 launched two new resources designed to increase access to information about contraceptive research and development (R&D) and to promote global knowledge sharing.
INTERGROWTH-21st Fetal Growth Standards

Has the prevalence of stunting in South African children changed in 40 years? A systematic review
by Said-Mohamed et alThe objective of this systematic review is to investigate the changes in the prevalence of stunting, a chronic form of undernutrition, in South Africa over 40 years, and to derive lessons from the South African experience, a country in an advanced process of transition in sub-Saharan Africa.
Intestinal parasitic infections are highly endemic among school-aged children in resource-limited settings. To lower their impact, preventive measures should be implemented that are sustainable with available resources. The aim of this study was to assess the impact of handwashing with soap and nail clipping on the prevention of intestinal parasite reinfections.

Maternal nutrition: how is Eastern and Southern Africa faring and what needs to be done?
by Salam et alThe progress in key maternal health indicators in the Eastern and Southern Africa Region (ESAR) over the past two decades has been slow. This paper analyzed available information on nutrition programs and nutrition-specific interventions targeting maternal nutrition in the ESAR and proposes steps to improve maternal nutrition in this region. Findings from the review suggest that multiple nutrition programs are in place in the ESAR; including programs that directly address nutrition indicators and those that integrate corresponding sectors like agriculture, health, education, and water and sanitation. However, their scale and depth differ considerably. These programs have been implemented by a diverse range of players including respective government ministries, international agencies, non government organisations and the private sector in the region. Most of these programs are clustered in a few countries like Kenya, Uganda and Ethiopia while others e.g. Comoros, Somalia and Swaziland have only had a limited number of initiatives.
