Prevalence of multiple micronutrient deficiencies amongst pregnant women in a rural area of Haryana

Deficiencies of micronutrients (zinc, iron, folic acid and iodine) during pregnancy are known causes of Low Birth Weight (LBW). Studies have documented status of one or two micronutrients amongst pregnant women (PW). However, no attempt has been made to concurrently assess the prevalence of multiple micronutrient deficiencies and the factors associated with them amongst PW.Objective: The present study was undertaken to assess the prevalence of multiple micronutrient deficiencies amongst PW in a rural area.Methods: A community based cross sectional survey was conducted in six villages of a rural area of district Faridabad in Haryana state, India during November 2000 and October 2001. All PW aged 18 years or more, with pregnancy duration of more than 28 weeks were enrolled. Data were collected on socio-economic status and other demographic parameters. Serum zinc, copper and magnesium levels were estimated by utilizing the Atomic absorption spectrophotometry (AAS); serum ferritin and folate was estimated by Enzyme Linked Immuno Sorbent Assay (ELISA) method and the Radio-lmmuno Assay (RIA) method, respectively and serum thyroid stimulating hormone (TSH) level was estimated by the Abbot AxSYM System. Serum zinc, copper, magnesium, ferritin, and folate levels less than 70.0 μg/dl, 80.0 μg/dl, 1.80 mg/dl, 15 ng/ml, and 3 ng/ml, respectively were considered as indicative of deficiency for respective micronutrients. The TSH levels of 4.670 and more indicated iodine deficiency status. Dietary intake of micronutrients was assessed utilizing 1-day 24-hour dietary recall methodology. Food consumption pattern was assessed utilizing the food frequency questionnaire methodology.Results: Nearly 73.5, 2.7, 43.6, 73.4, 26.3, and 6.4 percent PW were deficient in zinc, copper, magnesium, iron, folic acid and iodine, respectively. The highest concurrent prevalence of two, three, four and five micronutrient deficiency was of zinc and iron (54.9%); zinc, magnesium and iron (25.6%); zinc, magnesium, iron and folic acid (9.3%) and zinc, magnesium, iron, folic acid and iodine (0.8%), respectively. No pregnant woman was found to have concomitant deficiencies of all the six micronutrients. Dietary intake data revealed an inadequate nutrient intake. Over 19% PW were consuming less than 50% of the recommended calories. Similarly, 99, 86.2, 75.4, 23.6, 3.9 percent of the PW were consuming less than 50% of the recommended folic acid, zinc, iron, copper, and magnesium. The consumption of food groups rich in micronutrients (pulses, vegetables, fruits, nuts and oil seeds, animal foods) was infrequent. Univariate and Multivariate logistic regression analysis revealed that low dietary intake of nutrients, low frequency of consumption of food groups rich in micronutrients and increased reproductive cycles with short interpregnancy intervals were important factors leading to micronutrient deficiencies.Conclusion: There was a high prevalence of micronutrient deficiencies amongst the PW of the area, possibly due to the poor dietary intake of food and low frequency of consumption of food groups rich in micronutrients. The concurrent prevalence of two, three, four and five micronutrient deficiencies were common.

Role of trace elements zinc, copper and magnesium during pregnancy and its outcome.

Trace element deficiencies have been documented to play an important role in determination of the fetal outcome. Pregnant women in developing countries have been reported to consume diets with a lower density of minerals and vitamins. Deficiencies of trace elements like zinc, copper and magnesium have been implicated in various reproductive events like infertility, pregnancy wastage, congenital anomalies, pregnancy induced hypertension, placental abruption, premature rupture of membranes, still births and low birth weight. The present review article highlights the important of role played by zinc, copper and magnesium during pregnancy and its outcome. The role of individual trace elements and in combination with other trace elements has not been completely documented. There is a need to undertake further studies in this field.

Iron, folate, and vitamin B12 stores among pregnant women in a rural area of Haryana State, India.

Background Iron, folate, and vitamin B12 deficiencies have adverse effects on pregnancy outcome. In India, data on the concomitant prevalence of these deficiencies among pregnant women are meager. Objective We conducted a community-based study to assess the prevalence of deficiencies of iron, folate, and vitamin B12 among pregnant women in a rural block of Haryana State. Methods The study was approved by the ethics committee of the All India Institute of Medical Sciences, New Delhi. A total of 283 pregnant women were enrolled in the study. After oral informed consent had been obtained from the women, blood was drawn from the antecubital vein for estimation of the levels of serum ferritin by enzyme-linked immunosorbent assay (levels < 12 ng/mL were considered as indicative of poor iron stores); serum folate was determined by radioimmunoassay (levels < 3 ng/mL were considered as indicative of poor folate stores); and serum vitamin B12 was estimated by the microbiologic method (levels < 200 pg/mL were considered as indicative of poor vitamin B12 stores). Results The results indicated that 67.7%, 26.3%, and 74.1% of the women had poor iron, folate, and vitamin B12 stores, respectively. Concomitant deficiencies of iron, folate, and vitamin B12 occurred in 16.2% of the women. We found that 59.9% of the women were consuming less than 75% of the recommended daily caloric allowance (2,175 kcal), indicating an overall poor food intake. This could be one of the predominant reasons for poor iron, folate, and vitamin B12 stores among the women. Conclusions Our findings suggest that apart from iron and folate, vitamin B12 deficiencies may play an important role in causing anemia.

Prevalence of iron, vitamin A, and iodine deficiencies amongst Adolescent Pregnant Mothers

Objective : The present study was undertaken to assess the prevalence of iron, vitamin A and iodine deficiencies amongst rural Adolescent Pregnant Mothers (APM).Methods : Survey was conducted amongst APM in a rural block; district Udham Singh Nagar, Uttaranchal State. In the district, all blocks were enlisted and one block was randomly selected. Further, villages in the block were listed (n=64) and five villages were randomly selected for the detailed study. All APM residing in the selected villages were included for the detailed study. The data on socio demographic parameters was collected utilizing a pretested semi-structured questionnaire. Anaemia was assessed by hemoglobin estimation with the help of the HemoCue instrument. Vitamin-A deficiency (VAD) was assessed by presence of night blindness utilizing a pre-tested semi structured proforma. Iodine Deficiency was assessed by the clinical examination of the thyroid gland and estimating the Urinary Iodine Excretion (UIE) levels of each subject. Nutrient intake was assessed by the 24-hr dietary recall method.Results : One hundred and fifty one APM, belonging to low socio economic group, were selected for the study. The occupation of the families was farming, but the APM were housewives. The mean age of the APM was 17.8 ±1.5 yr. Eighty nine percent of the APM were in the age group 16–19 yr. Sixty percent of the APM were in the gestational age of 24 weeks and more. It was found that 46.0% of the APM were anaemic (Hb <11.0 gm/dl). Sixteen percent of the study subjects had presence of night blindness. Fifteen percent of the subjects had Goiter. Median UIE level in the subjects studied was 95.0 μg/l. Concomitant prevalence of the three deficiencies was amongst 2.0% of the population. The 24-hour dietary intake revealed that the mean consumption of retinol and iron was only 13 and 28% of the recommended dietary allowance, respectively.Conclusion : The findings of the present study indicated that Anaemia, Vitamin A, and Iodine deficiency existed as public health problems in the APM of the study area.

Magnitude of Zinc Deficiency among Nulliparous Nonpregnant Women in a Rural Community of Haryana State, India

Zinc deficiency during pregnancy affects the outcome of pregnancy. A high prevalence of zinc deficiency (55.5%) has been reported among pregnant women. It is not known whether pregnancy leads to zinc deficiency due to the increased fetal needs or whether the women are zinc deficient when they become pregnant. No data are available on the zinc status of nulliparous nonpregnant women from India. To assess the magnitude of zinc deficiency among nulliparous nonpregnant women in a rural community of Haryana State, India. A community-based cross-sectional survey was conducted in six villages of a rural area in a district of Haryana State, India. All nulliparous nonpregnant women aged 18 years or over who were willing to participate in the study were enrolled. Each woman was questioned about her age, socioeconomic status, and dietary pattern with the use of a pretested semistructured questionnaire. Blood from the antecubital vein was drawn to assess the serum zinc levels using an atomic absorption spectrophotometer. Serum zinc levels less than 70.0 μg/dl were considered to indicate zinc deficiency. The dietary intakes of zinc, protein, and calories were assessed by the 24-hour dietary recall method. Two hundred eighty-eight nulliparous nonpregnant women were enrolled. Forty-one percent had zinc deficiency, and 75.7%, 1.4%, and 7.3% of the women consumed less than 50% of the recommended intake of zinc, protein, and calories, respectively. Women who consumed less than 50% of the recommended intake of calories (1,875 kcal) were at a 4.9 times higher risk of zinc deficiency than women who consumed more than 50% of the recommended intake. A high prevalence of zinc deficiency was found among the nulliparous nonpregnant women in the area studied.

Elimination of iodine deficiency disorders in Delhi

Objective: The present study was conducted in year 2002 in NCT of Delhi with the objective to re-assess the prevalence of iodine deficiency disorders.Methods : A total of 7009 children in the age group of 6–11 years were clinically examined for presence of goiter. A total of 991 salt samples were also collected randomly. On the spot casual urine samples were collected from 1395 children.Results : The total goiter prevalence was found to be 6.2 %. The percentage of children with urinary iodine excretion (UIE) of <20.0, 20.0-<50.0, 50.0–99.9 and 100.0 Μg/l and above was 0.8, 1.8, 8.7 and 88.7%, respectively. The median UIE level was 200 Μg/L The assessment of iodine content of salt revealed that only 16% of the families were consuming salt with iodine content less than 5 ppm.Conclusion : The findings of the present study indicated that the population is in a transition phase from iodine deficient (as revealed by Total Goiter Prevalence) to iodine sufficient nutriture (as revealed by median UIE 200 Μg/l). A significant progress has been achieved towards elimination of IDD from NCT of Delhi.

Profile of iodine content of salt and urinary iodine excretion levels in selected districts of Tamil Nadu.

Objective. Iodine deficiency disorders (IDD) is the most common cause of preventable mental retardation in world today. Out of 29 districts in Tamil Nadu, 24 have been surveyed and all have been found to be endemic to IDD. There is a complete bah on the sale of non iodised salt in the state since 1995. The present study was conducted to assess the iodine content of salt and urinary iodine excretion levels amongst the beneficiaries in the state to help the government to strengthen the existing Universal salt iodisation (USI) programme activities.Methods:The study was undertaken in 24districts of Tamil Nadu during the year 2001. The guidelines recommended by WHO/UNICEF/ICCIDD for a rapid assessment of salt iodisation in a district was adopted. A minimum of 150 salt samples were collected from each district by utilising the uniform sampling methodology. The iodine content of salt samples was analysed using the standard iodometric titration method. At least 60 children from each school were randomly selected and were requested to provide “on the spot” casual urine samples. The urinary iodine excretion (UIE) levels were analysed using the wet digestion method.Results: It was observed that 62.3% of the families were consuming iodised salt with more than 5 ppm of iodine. It was found that district Perambalour had deficient iodine nutriture as revealed by the median UIE levels less than 100 μg/l.Conclusion: The findings of the present study reveals the success of USI programme and highlights need for continued monitoring of the quality of salt provided to the population in order to achieve the goal of IDD elimination.
