Anemia in relation to body mass index and waist circumference among chinese women

Abstract

BackgroundThis study aimed to investigate the relationship of anemia and body mass index among adult women in Jiangsu Province, China. Data were collected in a sub-national cross-sectional survey, and 1,537 women aged 20 years and above were included in the analyses. Subjects were classified by body mass index (BMI) categories as underweight, normal weight, overweight and obese according to the Chinese standard. Central obesity was defined as a waist circumference ≥ 80 cm. Anemia was defined as hemoglobin concentration < 12 g/dl. Prevalence ratios (PRs) of the relationship between anemia and BMI or waist circumference were calculated using Poisson regression.FindingsOverall, 31.1% of the Chinese women were anemic. The prevalence of overweight, obesity and central obesity was 34.2%, 5.8% and 36.2%, respectively. The obese group had the highest concentrations of hemoglobin compared with other BMI groups. After adjustment for confounders, overweight and obese women had a lower PR for anemia (PR: 0.72, 95% CI: 0.62-0.89; PR: 0.59, 95% CI: 0.43-0.79). Central obesity was inversely associated with anemia.ConclusionIn this Chinese population, women with overweight/obesity or central obesity were less likely to be anemic as compared to normal weight women. No measures are required currently to target anemia specifically for overweight and obese people in China.

Anaemia in Relation to Body Mass Index (BMI) and Socio- Demographic Characteristics in Adult Nigerians in Ebonyi State

“…This is in contrast with studies elsewhere [1,40,41]. In Chinese women from Jiangsu Province, an inverse association was found between overweight, obesity, central obesity and Anaemia [40].…”

“…This is in contrast with studies elsewhere [1,40,41]. In Chinese women from Jiangsu Province, an inverse association was found between overweight, obesity, central obesity and Anaemia [40]. Similarly, a negative association between hemoglobin concentration and BMI has been observed in medical students of Himalayan Institute of Medical Sciences [41].…”

Correlation Between Anthropometric Measurements and Risk of Anemia Among Rural Community in Cangkringan, Sleman

“…This means that the higher the WHR (the risk of abdominal obesity), the higher the Hb levels are. Therefore, the results of the study are not in accordance with the studies that have been done previously (Qin et al, 2013;Gartner et al, 2013).…”

“…A study in China by Qin et al (2013) concluded that in China, females with obesity/overweight or central obesity are more likely to have anemia than the female subjects with normal anthropometry. This especially increased in older patients.…”

The Relevance of Vitamin and Iron Deficiency in Patients with Inflammatory Bowel Diseases in Patients of the Swiss IBD Cohort

“…This finding is in line with the literature: subjects with normal BMI showed normal hemoglobin levels and less tendency to develop anemia. 35,36 Of note, smoking is clearly associated with folate and vitamin B12 deficiency in our SIBDCS patients. However, surprisingly, nonsmoking status is positively associated with anemia in CD patients.…”
