Association between dietary patterns and anaemia in adults from Jiangsu Province in Eastern China

Abstract

The objective of the present study was to investigate the association between food patterns and anaemia among Chinese adults. It was a crosssectional household survey undertaken in 2002. The sample contained 2849 men and women aged 20 years and above, and had a response rate of 89·0 %. Factor analysis was used to identify food patterns based on a food-frequency questionnaire. Logistic regression was used to relate food patterns to anaemia. A four-factor solution explained 30·5 % of the total variance. After adjusting for socio-demographic factors and four distinct food patterns, the 'traditional' (rice, vegetable, wheat flour), 'sweet tooth' (drinks, cake) and 'healthy' (whole grains, fruits, vegetables) patterns were independently associated with anaemia. 'Traditional' and 'sweet tooth' patterns were positively associated with anaemia, whereas the association with 'healthy' food pattern was negative. No association was observed between the 'macho' pattern (meat and alcohol) and anaemia. Compared with the lowest quartile (Q1) of the 'traditional' pattern, the highest quartile (Q4) had a higher risk of anaemia (men: odds ratio (OR) 2·60, 95 % CI 1·38, 4·88; women: OR 3·40, 95 % CI 2·14, 5·39). For the 'sweet tooth' pattern, compared with the lowest quartile (Q1), the OR of the highest quartile was 2·34 (95 % CI 1·47, 3·73) for men and 2·02 (95 %CI 1·31, 3·13) for women. The fourth quartile of healthy food was associated with a lower risk of anaemia (men: OR 0·50, 95 % CI 0·31, 0·79; women: OR 0·51, 95 % CI 0·34, 0·75). Women in the north had a higher risk of anaemia (OR 2·49, 95 %CI 1·80, 3·43). Food patterns were associated with anaemia in this area with a high prevalence of anaemia.

Vegetable-rich food pattern is related to obesity in China

“…The food patterns were found to be associated with anemia in a previous article based on the same sample. 15 The vegetable-rich food pattern was characterized Active commuting including walking and cycling. Vegetable-rich food pattern and obesity in China Z Shi et al by high intake of fruits, vegetables, whole grains, animal foods, milk and eggs.…”

“…A multistage cluster sampling method was used to select the participants. 15 The data presented in this article are based on a subsample from Jiangsu province, one of the economically booming areas in China with a population of 73.6 million. The rural sample was selected from six counties (Jiangyin, Taicang, Suining, Jurong, Sihong and Haimen).…”

“…A similar 'prudent/healthy' pattern is found and is negatively associated with anemia and mortality. [15][16][17][18][19] The objective of the present article is to look at the association between a vegetable-rich food pattern derived from factor analysis and the risk of obesity in Chinese adults.…”

Association of dietary pattern and body weight with blood pressure in Jiangsu Province, China

“…The study was conducted in Jiangsu Province using a multistage cluster sampling method, as described previously [19, 20], which was part of the 2002 National representative cross-sectional survey in nutrition and health. Six counties and two prefectures represented a geographically and economically diverse population for Jiangsu Province.…”

The Relative Validity and Reproducibility of an Iron Food Frequency Questionnaire for Identifying Iron-Related Dietary Patterns in Young Women

“…15 However, only a handful of studies have investigated the validity of dietary patterns determined using factor analysis based on a FFQ by comparing it with the gold-standard diet record, 16 -21 and only two of these studies have considered the reproducibility of dietary patterns obtained using an FFQ by comparing it with the same FFQ completed at a later date. 19,21 Neither of the studies that have considered the effect of dietary patterns on iron status 12,13 have reported the validity of their FFQ for determining dietary patterns.…”
