Humans exhibit considerable diversity in timing and rate of reproduction. Life-history theory (LHT) suggests that ecological cues of resource richness and survival probabilities shape human phenotypes across populations. Populations experiencing high extrinsic mortality due to uncertainty in resources should exhibit faster life histories. Here we use a path analytic (PA) approach informed by LH...

As 2015 quickly approaches, we have been made increasingly aware of our progress toward Millennium Development Goals (MDGs). However, one MDG has been particularly recalcitrant to progress: MDG 5, namely, improving maternal health. Few countries are on track to achieve the first part of MDG 5's goals, reducing maternal mortality by 75%. This article addresses the key priority issues of maternal...

The issues of contraception and family planning have been particularly sensitive and complex in sub-Saharan Africa. Family planning programs which promote the use of safe and effective modern methods of contraception have generally not been well received on the continent. The reality, however, is that sub-Saharan Africa has a rapidly growing population in the context of the world's least deve...

OBJECTIVE To present estimates of maternal mortality in 188 countries, areas, and territories for 1995 using methodologies that attempt to improve comparability. METHODS For countries having data directly relevant to the measurement of maternal mortality, a variety of adjustment procedures can be applied depending on the nature of the data used. Estimates for countries lacking relevant data m...

We examine progress towards the 1994 International Conference on Population and Development (ICPD) commitment to provide universal access to sexual and reproductive health (SRH) services by 2014, with an emphasis on changes for those living in poor and emerging economies. Accomplishments include a 45% decline in the maternal mortality ratio (MMR) between 1990 and 2013; 11.5% decline in global u...

BACKGROUND Upon emergence from their pupal cells, bollworm, Helicoverpa zea (Boddie), adults actively seek and feed on plant exudates before they disperse and reproduce on suitable host plants. This nocturnal behavior of the bollworm may be exploited as a pest management strategy for suppression of the insect by using an attractant/stimulant mixed with an insecticide to induce feeding to cause ...

BACKGROUND Maternal mortality remains a severe problem in many parts of the world, despite efforts to reach MDG 5. In addition, underreporting is an issue especially in low income countries. Our objective has been to identify the magnitude of maternal deaths and the degree of underreporting of these deaths in Accra Metropolis in Ghana during a one year period. METHODS A Reproductive Age Morta...

OBJECTIVES The aims of the study were to determine the prevalence, types and socio-economic correlates of consanguineous marriages in Iran, and to gauge the extent to which consanguinity influenced fertility, pregnancy outcomes and the expression of genetic disorders in the present-day population. METHODS Data on the prevalence of consanguinity and birth outcomes in the first marriages of 5,5...

Beginning in 1990, Mongolia, a former client state of what was then the Soviet Union, undertook liberal economic reforms. These came as a great shock to Mongolia and Mongolians, and resulted in food shortages, reports of famine, widespread unemployment, and a collapse of public health and health care. Although economic conditions have stabilized in recent years, unemployment and poverty are sti...
