Study on the status and change for dietary energy and pattern in Tianjin residents

Objective To analyze the status and trend of dietary energy and pattern of Tianjin residents, so as to provide data and basis for carrying out nutrition intervention and policy making. Methods Data used to analyze comes from Chinese residents' nutrition and health status monitoring from 2010 to 2012 in Tianjin area. The 24h dietary recall method for 3 consecutive days was used in dietary survey and weighing method was used for condiment intake. The sample includes 1 268 persons from 536 families in the whole city including urban area, suburb and rural area. Results Tianjin residents' standard energy intake per person per day was 2 208.48 kcal, basically meeting the need. The proportion of energy providing in protein and fat was 13.05% and 35.80% respectively; the energy supply proportion of fat slightly rised compared with that in 2002. The energy supply proportion of grain was obviously low (49.74%); the energy supply proportion of animal food and pure heat food are both on the high side (16.25%, 17.67%). The intake of protein was up to 70.20 g and the proportion of protein from grain was 41.98%, obviously higher than that in 2002. The proportion of grain decreases and was obviously lower. The intake of dietary fat was 79.53 g, which was higher than that in 2002. Conclusions In recent 10 years, dietary energy of Tianjin residents rise while the energy supply proportion of grain obviously descends; the intake of protein and fat both obviously increases; the dietary pattern gradually deviates from traditional dietary pattern in grain taking. Now the pattern turns to the high-energy, high-fat and high-protein western dietary pattern with pure heat food such as animal food and oil fat and. The condition was unoptimistic and the positive and effective measure should be taken.
