Child feeding recommendations include breastfeeding beyond 12 months, however, some researchers have reported increased rates of malnutrition in breastfed toddlers. A negative association between growth and breast-feeding may reflect reverse causality; that is, the outcome (growth) is a determinant of the predictor (breastfeeding), and not vice versa. We examined this question with data from 134 Peruvian toddlers. ⋯ The negative association between breastfeeding and linear growth reflected reverse causality. Increased breastfeeding did not lead to poor growth; children's poor growth and health led to increased breastfeeding. Children's health must be considered when evaluating the association of breastfeeding with anthropometric outcomes.

Maternal mortality ratios in Kasama and Kaputa Districts, two remote rural areas of Northern Province, Zambia, were suspected to be very high. In order to evaluate the impact of a referral system baseline maternal mortality levels and additional maternal mortality risk arising from poor accessibility were estimated. ⋯ This study suggests that solving the accessibility problem would decrease the mortality burden from maternal causes with at least 29% in Kasama District and 65% in Kaputa District.

Trends of liver cirrhosis mortality in Europe, 1970-1989: age-period-cohort analysis and changing alcohol consumption.
Since the mid 1970s, a striking reduction in alcohol-related problems has been observed in many Western countries. Liver cirrhosis mortality is considered to be a major indicator of alcohol-related problems in the general population. The aim of the present study is to describe liver cirrhosis mortality trends in European countries between 1970 and 1989. ⋯ The age-period-cohort analysis allows targeting of health care and prevention programmes based on future trends. Aetiological and prognostic factors act differently in Europe. A better understanding of the trends would require more detailed information on alcoholism treatment rates, alcohol habits, viral hepatitic infections and other factors involved in the aetiopathogenesis of the disease.

Child mortality estimates in Beirut are presented for the late 1970s and the mid 1980s, and changes in socio-religious differentials of mortality across time are investigated. ⋯ The findings confirm the hypothesis of a reduction over time of religious-based child mortality differences in the capital city of Lebanon, in agreement with the pattern found for religious-based fertility differences. Comparisons with other countries in the region indicate that the war in Lebanon has slowed down the decline in child mortality, causing the country to loose its priviledged position among Arab countries.

Studies examining the associations between short birth spacing and child mortality have often concentrated on the strength of the associations whilst the public health importance of short spacing in specific communities has received less attention. This study re-examines the association between short birth intervals and child mortality in rural Senegal and discusses the potential direct effects of efforts to delay births on child mortality in this community. ⋯ In this community where prolonged breastfeeding causes women to space their births at long intervals, short birth intervals are a consequence rather than a cause of child mortality and the potential direct effects of birth spacing efforts on child mortality are limited. To reduce the high levels of child mortality, efforts will have to be made to ensure effective preventive and curative health services, and to maintain the traditional pattern of breastfeeding.
