Seasonal patterns of birthrates and birthweights have been compiled from the delivery records of 11 rural hospitals and compared with each other and with the local rainfall pattern by means of lagged regression analysis. While mean birthweight is lower in high rainfall areas, both magnitude and predictability of seasonal birthweight variations are greater in low rainfall areas. Such differences are attributed to different combinations of infection rates, dietary intake and reliability of food supply. Seasonal variations in birthrate were found to occur independently from those of birthweight. Birth seasonality was found to be prominent only in areas with holoendemic malaria and is attributed to a seasonal depression of fecundity mainly due to malaria infection.
已根据11家农村医院的分娩记录编制了出生率和出生体重的季节性模式，并通过滞后回归分析将它们相互比较，还与当地降雨模式进行了比较。虽然高降雨地区的平均出生体重较低，但低降雨地区出生体重季节性变化的幅度和可预测性更大。这些差异归因于感染率、饮食摄入量和食物供应可靠性的不同组合。发现出生率的季节性变化与出生体重的季节性变化相互独立。仅在疟疾高度流行的地区发现出生季节性较为突出，这归因于主要由疟疾感染导致的生育力季节性下降。
