Cross-sectional Study On Fat Intake And Corelates In Shanghai

[Objective]To collect information of dietary fat intake among 15 and more than 15 years old residents in Shanghai and study its risk factors. To provide scientific evidences for non-communicable chronic diseases prevention’s policy making.[Methods]Multi-staged stratified sampling was used.15 and more than 15 years old subjects were sampled by four stages in Shanghai. Face to face interview was to collect basic information of subjects’household, physical activities, etc. Dietary survey was to collect information of food and condiments intake. Sample weight was set up according to Shanghai population. Data was analyzed by SAS 9.3.[Results]Population of 15 and more than 15 years old in Shanghai had average energy intake per day as 2229.5kcal, total fat intake as 88.6g, energy proportion contributed from fat as 36.1%, SF intake as 19.3g, MUSF intake as 31.4g, PUSF intake as 25.7g, n-6 PUSF intake as 12. 1g, n-3 PUSF intake as 1.0g, cholesterol intake as 443.3mg. There were only 22.0% population of 15 and more than 15 years old whose energy proportion contributed from fat were subject to recommendation, and 73.2% exceeded recommendation. S:M:P was 1.0:1.7:1.5. n-6/n-3 PUFA was 18.0.43.9% fat intake was from cooking oil and 40.4% was from animal food. 31.5% SF intake was from cooking oil and 61.2% was from animal food. 40.5% MUSF intake was from cooking oil and 53.0% was from animal food. 67.7% PUSF intake was from cooking oil and 18.9% was from animal food. 74.1% n-6 PUSF intake was from cooking oil and 8.2% was from animal food. 62.6% n-3 PUSF intake was from cooking oil and 14.7% was from animal food. 98.7% cholesterol intake was from cooking oil, including 23.9% was from the meat. Age and years of education were in reverse relationship with energy proportion contributed from fat.[Conclusion] The population’s energy proportion contributed from fat exceeded recommendation with no significant difference from that of 10 years ago, but urban and rural area situation was reversed for the first time. About three quarter population of 15 and more than 15 had a high proportion of fat in their diet which showed high fat intake dietary patterns. Dietary fat mainly came from cooking oil and meat. The probable helpful n-3 PUFA intake was low. Too much cholesterol intake and more than half population’s intake exceeded recommendation. Compared with 10 years ago, energy and fat intake of population of 15 and more than 15 years old in Shanghai decreased significantly. Age and years of education were risk factor of high fat intake dietary pattern. It was recommended that carry out nutrition campaign in Shanghai themed as "low fat intake, low cholesterol intake" and provide recommendations which are adjust proportion of animal food intake as reducing meat and increasing sea food intake.
