Prevalence of zinc deficiency among rural women during childbearing age in Peshawar, Pakistan

ABSTRACT

Zinc deficiency is a commonly reported health problem throughout the world. This cross sectional survey was conducted in rural Peshawar with an aim to estimate the prevalence of zinc deficiency in women of child bearing age and find its association with age, marital, pregnancy status and parity. Data was collected from 353 women age 15-45 years. EPI INFO version 6.04 was used for data analysis. Overall 98 [27.8%] women were zinc deficient [zinc deficiency [<50microg/dl.]. Mean zinc level was found to increase gradually with the increase in the age up to 40 years and then starts decreasing significantly beyond this age. A significant decrease [p<0.03] in zinc concentration was found in married as compared to unmarried women. Out of 31 female with severe zinc deficiency, 23 [74.2%] were pregnant. Pregnant women in second [OR [CI] 3.36 [1.52-7.44] p<0.0008] and third [OR [CI] 3.73 [1.91- 7.30] p<0.00002] trimester were 3.4 and 3.7 times, respectively more zinc deficient as compared to control women. Mean zinc levels were significantly lower in women having no children versus women with 1-5 numbers of children. This study concludes that severe zinc deficiency especially prevalent in pregnant women needs urgent correction through food supplementation.
