Abstract: Objective To study the edible oil intakes among Guangdong residents between 2002 and 2012 and to provide evidence for developing strategies to intervene their intake of edible oil. Methods Using multi stage stratified cluster sampling, 8 counties were selected from 1 large city, 1 medium sized and small city and 6 rural areas in 2002; 6 resident/village committees were randomly selected in each county and 30 households were then randomly sampled from each resident/village committee. Seven counties were selected from 2 large cities, 3 medium sized and small cities and 2 rural areas; 6 resident/village committees were randomly selected in each county and 30 households were then randomly sampled from each resident/village committee in 2012. Family members aged 2 years and over were interviewed adopting the method of questionnaires and dietary surveys. Contents of the questionnaire included socio demographic characteristics and economic income of the participants. The gravimetric method was used for dietary surveys. Data of the surveys were analyzed by using descriptive epidemiological method. Results A total of 4 801 residents (2 408 males and 2 394 females) and 3 222 residents (1 466 males and 1 756 females) aged 2 years and over were investigated in 2002 and 2012, respectively. The average daily edible oil intakes were 31.2, 33.1, and 33.8 g in 2002, and 43.7, 32.1, and 32.0 g in 2012 for residents in large, medium sized and small cities, and rural areas in Guangdong, respectively. Percentages of edible oil daily intake per person were 21.5%(117/544), 24.8%(129/521), and 39.7%(1 483/3 736)in 2002,and 35.1%(279/795), 24.8%(374/1 509), and 29.1%(267/918)in 2012, respectively, for residents in large, medium sized and small cities, and rural areas, exceeding the Recommended Daily Allowances (RDA) of the Dietary Guidelines for Chinese Residents. The percentage of residents whose edible oil intakes exceeded RDA to the total number of survey population was significantly decreased from 36.0% (1 729/4 801) in 2002 to 28.6% (920/3 222) in 2012 (P<0.01). The differences of percentages exceeding RDA for edible oil intakes were statistically significant in three areas in 2002 (P<0.01), of which the percentage in rural areas was all higher than the ones in the large, medium sized and small cities ( all P<0.01). The differences of percentages exceeding RDA for edible oil intakes were statistically significant in three areas in 2012 (P<0.01), of which the percentage in large cities was higher than the ones in medium sized and small cities and rural areas (all P<0.01). Conclusion Compared with 2002, the percentage of exceeding RDA for edible oil intakes was decreased in 2012. However, the health education still needs to be strengthened.
