RESUMEN
Among the three major components of a closed birth interval, waiting time to conception can somehow be managed with effective contraceptives while gestation is universally constant in its duration; the duration of postpartum amenorrhoea (PPA) varies in complex nature. The present study aimed to investigate the proximate factors influencing the duration of PPA. A community-based, cross-sectional study was conducted in four valley districts of Manipur, India, during 1 August−31 December 2009, to analyze the differentials and determinants of duration of PPA, applying the survival analysis technique. In total, 1,225 ever-married women were selected through two-stage cluster sampling. The median duration of PPA was 5.7 months. Among the 11 explanatory variables of interest, only three variables—place of residence (p<0.05), infant mortality from preceding pregnancy (p<0.01), and duration of breastfeeding (p<0.01)— had a significant effect on the duration of PPA. The findings may be used as baseline information for future researchers and maternal health policy-makers.
RESUMEN
726 urban school-going children in the age group 5-16 years were screened during the period from February to May, 1980 at Imphal. The growth rate of girls was apparently faster than that of boys as evidenced from the increment nature of height and weight per annum. Growth spurts were observed during the age group of 6-8 years and 12-13 years for boys, and 5-8 years and 11-12 years for girls. The height pattern of these children was significantly higher than the Indian standard height. However, weight was more or less similar with the Indian standard.
