This paper examines the association between infant mortality of the first born and subsequent children using data from rural Bangladesh collected during the period 1971-82. It shows that birth spacing and age of mother at the time of the second birth are important predictors of the survival status of the first child. The findings are discussed in terms of policy implications.
The present study aimed to assess the metabolic consequences of the chronic ingestion of two starches giving different postprandial glycaemic responses in normal and diabetic rats. The two starches chosen were mung-bean (Phaseolus aureus) starch (97% pure starch) and wheat starch presented as ground French toast. First, we studied the characteristics of these two starches. In vitro the alpha-amylase (EC 3.2.1.1) digestibilities of these starches were 40 (SE 3) and 62 (SE 4)% respectively at 30 min, whereas the contents of resistant starch were 77 (SE 4) and 22 (SE 4) g/kg respectively. In vivo the mung-bean starch produced lower postprandial glycaemic responses than the wheat starch (areas under the curve were: 91 (SE 28) and 208 (SE 33) mmol.min/l, P < 0.05) in normal rats (n 8). We then submitted twenty-eight normal and twenty-eight diabetic (neonatal streptozotocin on second day of birth) male Sprague-Dawley rats (6 weeks old) to a diet containing 570 g starch/kg as either mung-bean starch or wheat starch (n 14 rats/group). After 5 weeks on the diets food intakes and body weights were identical in each group. Liver and kidney weights were comparable when expressed as relative weight. The mung-bean-starch diet slightly decreased epididymal fat-pad weight (P < 0.14, ANOVA) and led to a marked decrease in adipocyte volume (P < 0.05). Plasma triacylglycerol and phospholipid concentrations were lower after the mung-bean-starch diet than after the wheat-starch diet in both normal and diabetic rats, whereas free fatty acid concentrations were lower only in normal rats. Similarly, non-fasting plasma glucose concentrations decreased (P < 0.05) in normal rats fed on mung-bean starch but not in diabetic ones (P < 0.14). Insulin levels tended to be lower, but not significantly, after mung-bean-starch feeding than after wheat starch. We conclude that the replacement of 570 g wheat starch/kg diet with mung-bean starch for 5 weeks resulted in (1) lowered non-fasting plasma glucose and free fatty acid levels in normal but not in diabetic rats, (2) a reduction in plasma triacylglycerol concentration and adipocyte volume in both normal and diabetic rats. Thus, the type of starch mixed into the diet may have important metabolic consequences in normal and diabetic rats.
This retrospective study audited all the extrahepatic biliary operations performed through a subcostal muscle splitting incision between January, 1979 and June, 1995. Of the 400 patients subjected to biliary surgery 340 (85%) were females and 60 (15%) males. One hundred and eighty (45%) patients presented with symptoms of acute and 220 (55%) with chronic cholecystitis. Most (95%) of the operations were performed electively. Simple cholecystectomy was performed in 320 (80%) patients and 72 (18%) had common bile duct exploration for stones. Of these 67 had choledochoduodenostomy and 5 a polythene tube drainage of common bile duct. The overall morbidity of the procedure was 13.5% of which 3.5% were procedure related complications and 10.0% general complications. Only two deaths occured during the study giving a mortality of 0.5%. This technique has greatly reduced the hospital stay, the amount of blood loss during operation and post operative pain. No patient had incisional hernia or wound dehiscence and all the patients were back to work early. The results of this study suggest that this incision may be used with advantage elsewhere.
Infant and child mortality levels and trends in Bangladesh are examined using data from the 1989 Bangladesh Fertility Survey. Both infant and child mortality declined from the mid 1970s but infant mortality declined more quickly. The level of infant mortality in 1989 was around 100 per 1000 live births while child mortality (5q0) was 200 per 1000 live births. Life table analysis confirms the change in infant and child mortality. The decline in infant mortality is attributed to the introduction of improved public health measures and access to maternal and child health services.
A comparison of contraceptive and fertility data for 1985-91 with data for 1983 shows that fertility has continued to decline in Bangladesh, in all segments of society. The magnitude of decline varied according to educational level, region and urban-rural locality. The percentage decline in total marital fertility rate was somewhat higher among urban than rural residents; educated women showed greater declines than uneducated, increasing the overall educational differences in total fertility by 1991. Factors contributing to the recent decline in fertility are discussed.
Factors affecting desired family size in rural Bangladesh are examined using data from contraceptive prevalence surveys conducted between 1983 and 1991. The analysis suggests that mothers having two sons and one daughter are more inclined to perceive their family as complete than those having three sons and no daughter. Logistic regression analysis indicates that important determinants of desire for more children are age of woman, current contraceptive use status, work status, and family planning worker's visit. The policy implications of these findings are discussed.
"This study attempts to estimate by indirect estimation technique the levels of infant and child mortality in Bangladesh using the 1989 Bangladesh Fertility Survey (BFS). The levels of infant and child mortality obtained from the 1989 BFS indicate substantial improvements in child survival, although the fall in infant mortality has been faster than the fall in child mortality."
