  In this study determination of arsenic (As) contamination in the drinking water and urine of children along with its effect on their health status and intellectual functioning was assessed. The study was carried out in order to determine any correlation between intake of arsenic and intellectual functioning level of the children. Raven Standard Progressive Matrices (RPM) was administered on children of (8-15) years of age to assess their intellectual functioning and their health status was checked by measuring their height and weight. Water and urine sample were studied in both experimental and control group. In experimental area Arsenic level was above the World Health Organization (WHO) permissible value which was compared with control area having arsenic level below WHO permissible value in both water and urine. An average 45% of arsenic level in drinking water samples was above WHO permissible value (10 μg/L). Considering urinary arsenic as a biomarker of exposure to arsenic through drinking water, it was found that an average of 50% of children of the experimental group were found to have arsenic in their urine ranging from a concentration of 0.01-0.0119 μg/L. Conclusively, this study showed that the intellectual functioning level of children drinking arsenic contaminated water was significantly lower as compared to those, drinking arsenic-free water.

  To study the effect of age, gravidity, interval since last pregnancy and socioeconomic status (education and per capita income) on the development of iron deficiency anaemia in pregnant women. This descriptive study was conducted at the antenatal clinic of tertiary care hospital in Lahore. 150 pregnant women (50 in each trimester), attending antenatal clinic of tertiary care hospital was selected randomly. Information about socioeconomic and gestational status was collected with the help of semi structured questionnaire while 5cc venous blood was also collected for the estimation of Hemoglobin (Hb), Packed Cell Volume (PCV) and Mean Corpuscular Hemoglobin Concentration (MCHC). Diagnosis of iron deficiency anemia was based on history, percent hemoglobin and packed cell volume. In 150 selected patients, 80% had Hb within the range of 9-12 g/dl. Occurrence of anemia was most common in the age group of 20-30 years and it has statistically significant adverse effects on Hb level. It was also found that the Hb concentration was related to educational status of the pregnant women and Hb level improved significantly (p<0.05) with the increase in per capita family income. A directly proportional relationship of PCV and MCHC was found with Hb concentration. Fewer children, greater intervals between pregnancies and better socioeconomic status lead to lower probability of iron deficiency anemia during pregnancy.
