Malnutrition, defined as ill health caused by deficiencies of calories, protein, vitamins, and minerals interacting with infections and other poor health and social conditions, saps the strength and well-being of millions of women and adolescent girls around the world. though malnutrition actually also relates to problems of nutritional excess. Objectives: To assess the level of malnutrition among adult women by using Mid Upper Arm Circumference (MUAC) versus Body Mass Index (BMI),To correlate the mid upper arm circumference (MUAC) and Body Mass Index (BMI) among adult women ,To associate the level of malnutrition among adult women with their selected demographic variables. Research Methodology: A comparative descriptive design and quantitative research approach was adopted. 100 samples who are all adult women was selected for the study by using purposive sampling technique and the study was done at SMVMCH by using MUAC and BMI score. Result: Frequency and Percentage wise Distribution of nutritional Variables among adult women’s. Out of the 100 adult women’s who were interviewed, Majority of the adult women’s 98 (98%) of study population were no decreased in food intake in declined food intake over the past 3 month. Most of the adult women’s 95 (95%) were no weight loss in during last 3 month. Majority of the adult women’s 92 (92%) were independently do the routine .Most of them, were not experienced in having any chewing (or) swallowing difficulty 99 (99%). Majority of the adult women’s are followed any prescribed drug 97 (97%). Majority of the adult women’s 36 (36%) were not experienced eating fruits and vegetables.

Majority of them 212 (53%) were in View self as being no nutritional problem 87 (87%). Most of the adult women’s 97 (97%) were experienced in having any psychological disturbance 99 (99%).Frequency and percentage wise distribution of the level of the malnutrition among adult women by using Mid Upper Arm Circumference (MUAC). Majority of the adult women 28 (28%) had normal and obese level of malnutrition, 21 (21%) had more obese level of malnutrition, 13 (13%) had over weight level of malnutrition and less number had under- weight level of malnutrition 10 (10%).Frequency and percentage wise distribution of the level of the malnutrition among adult women by using Body Mass Index (BMI) - ASIAN CRITERIA. Majority of the adult women 32 (32%) had pre- obese level of malnutrition, 24 (24%) had normal weight level of malnutrition, 19 (19%) had obese level of malnutrition, 17 (17%) had over weight level of malnutrition and less number had under- weight level of malnutrition 8 (8%). Frequency and percentage wise distribution of the level of the malnutrition among adult women by using Body Mass Index (BMI) - WHO CRITERIA. Majority of the adult women 39 (39%) had normal weight level of malnutrition, 31 (31%) had pre-obese level of malnutrition, 16 (16%) had obese- I level of malnutrition, 8 (8%) had under- weight level of malnutrition and less number 4 (4%) had over weight level of malnutrition. Conclusion: A study to assess the malnutrition among adult women by using Mid Upper Arm Circumference (MUAC) Versus Body Mass Index (BMI) at Thirubhuvanai Palayam. The findings of the study revealed that out of 100 adult women, the level of the malnutrition among adult women by using Mid Upper Arm Circumference (MUAC),Body Mass Index (BMI) - ASIAN criteria and Body Mass Index (BMI) - WHO criteria in 28 (28%) had normal and obese level of malnutrition,32 (32%) had pre- obese level of malnutrition and 39 (39%) had normal weight level of malnutrition.
