    Dietary antioxidants and lipid profile of smokers
    (Department of Home Science, College of Agriculture, Vellayani, 2002) Prethi, N R; KAU; Nandini, P V
    The study entitled 'Dietary antioxidants and lipid profile of smokers' comprises information on the influence of various socio - economic and dietary profiles, as well as smoking habits on the health profile of selected respondents. The study was conducted among 100 adult males, who used more than 10 cigarettes a day and were in the habit of smoking for at least the past 10 years. Analysis of the smoking habit of respondents revealed that more than 50 per cent of the respondents were in the habit of smoking 10 to 15 cigarettes a day, while 14 per cent smoked more than 30 cigarettes a day. More number of them had been smoking for the past 10 to 15 years. The socio-economic profile of the smokers indicated that most of the respondents were in the age group of 36 to 40 years. Majority of the respondents were having an educational status of high school level. The occupational distribution of the respondents were more or less the same. Most of the respondents were married and were residing in nuclear families with four members. Majority of the respondents surveyed were having a monthly income between Rs. 2501 to 5000 On assessing the frequency of use of antioxidant rich food items. most of them used foods like milk and fats and oi Is most frequently while the least popular foods were flesh foods. Assessment of the influence of Smoking Index (SI) developed upon the various variables revealed that socio-economic profile and anthropometry has a strong influence on SI. Influence of SI on the anthropometry revealed significant negative correlation with MUAC, TST and weight, whereas no particular influence of a SI observed on the dietary pattern. Analysis of data pertaining to actual food intake revealed that the diets of respondents were inadequate and insufficient except for roots and tubers and milk. Nutrient intake of the respondents also did not meet the RDA specifications especially calorie, protein, iron and vitamin A. The serum analysis of the respondents revealed that smokers have reduced levels of serum antioxidants and elevated levels of serum lipid profile, when compared with normal standards. Assessment of the influence of different food groups upon the serum anti oxidant and lipid profile revealed that consumption of antioxidant rich foods not only helps to Improve the serum antioxidant profile but also helps to control the serum lipid profile. Frequent consumption of fat rich foods were found to increase the serum lipid profile. Frequent consumption of fat rich foods were found to increase the serum lipid profile while not influencing the serum antioxidant constituents. Data regarding the association between the serum profile and SI of the respondents revealed a significant positive association with total cholesterol and triglycerides.
