Using the data of China National Nutrition and Health Survey, we explored the relationship between dietary fructose intake and lipid indexes and dyslipidemia of 27 265 Chinese residents aged 45 and above. The level of serum total cholesterol (TC), triglycerides (TG) and high-density lipoprotein Cholesterol(HDL-C) were significantly lower in male while dietary fructose intake was lower in female (P < 0.001).With the increase of the dietary fructose quartile level, serum TG concentration was increased while HDL-C was decreased for male residents (Ptrend < 0.001). Among female residents, we only found serum TG concentration was increased (Ptrend < 0.001). Compared with the first quartile, the risk of low HDL cholesterolemia in the third (OR: 1.17; 95%CI: 1.03～1.33) and fourth (OR: 1.25; 95%CI: 1.08～1.43) quartile were increased after adjustment for confounding factor. There was no association between dietary fructose intake and hypercholesterolemia, hypertriglyceridemia, mixed hyperlipidemia, and dyslipidemia among female residents after adjustment for confounding factor (P > 0.001). There were gender differences for the effect of dietary fructose intake on lipid indexes and dyslipidemia.

Objective: To study the risk factors on anemia among elderly women in rural areas of Xiuning county, Anhui province, China., Methods: Xiuning county was selected as working field and elderly women aged 50-75 y were selected as subjects. Finger hemoglobin (Hb) was measured and basic health survey was face-to-face interviewed. 220 elderly women with anemia entered into the case group; and matched by age, another 220 women with normal Hb concentration entered the control group. Survey on diet, questionnaire regarding health and lifestyle and related blood indexes were studied and tested., Results: When comparing the data from both case and control groups, weight was (49.4 +/- 7.3) kg vs. (52.5 +/- 8.4) kg (t = 3.97, P < 0.01), waist circumference was (75.8 +/- 7.8) cm vs. (79.1 +/- 9.3) cm (t = 3.85, P < 0.01), BMI was (21.8 +/- 2.6) kg/m2 vs. (22.9 +/- 3.2) kg/m2 (t = 3.775, P < 0.01), respectively. The total protein was (76.4 +/- 5.0) g/L vs. (78.4 +/- 5.6)g/L (t = 3.83, P < 0.01), albumin was (45.7 +/- 3.1) g/L vs. (47.3 +/- 2.9)g/L (t = 5.24, P < 0.01), serum iron was ( 10.3 +/- 4.1) micromol/L vs. (12.7 +/- 4.6) micromol/L (t = 5.48, P < 0.01), and saturation of transferrin was (19.0 +/- 7.6)% vs. (23.1 +/- 9.1) % (t = 4.90, P < 0.01), respectively. Results from multifactor conditioned logistic regression analysis showed that the odd ratios (OR) for anemia with staple food, BMI and vitamin A were 1.54, 1.89, 1.69, and the OR for anemia with BMI, staple food, animal food, carbohydrate and vitamin A were 2.0, 1.6, 1.6, 1.4, 1.6, with their confidence intervals (CI) as 1.3-2.9, 1.1-2.3, 1.0-2.3, 1.0-2.1, 1.1-2.4, respectively., Conclusion: The quality of diet, health status and related blood indexes on anemia among elderly women were lower than that in control group. Lower BMI, less staple food and animal food, less carbohydrate and vitamin A intake appeared to be risk factors of anemia.

Objective: To study the related risk factors of anemia of rural elderly women in Huangling county, Shanxi, northwest of China., Methods: Elderly women aged 50-75 years in Huangling (northwest of China) were selected as study objects. Finger hemoglobin (Hb) was measured and basic health survey was face-to-face questioned. Two-hundred anemia elderly women were entered into the case group; and by age-matching, 200 with normal Hb concentration were entered into the control group. Dietary survey, health and lifestyle questionnaire were undertaken, and related blood indexes were tested., Results: In case and control group, annual income was (446.1 +/- 107.9) vs (903.8 +/- 179.1) yuan (t = 3.06, P < 0.01), daily average physical active time was (9.6 +/- 3.2) vs (10.3 +/- 3.1) hours (t = 1.94, P < 0.05), proportion of experiencing food scarce period was 31.8% vs 22.6% (chi2 = 4.14, P < 0.05), waist circumference was (76.2 +/- 7.3) vs (79.5 +/- 8.9) cm (t = 4.08, P < 0.01), respectively; the total protein was (78.0 +/- 5.8) vs (81.9 +/- 6.0) g/L(t = 5.94, P < 0.01), serum iron was (13.9 +/- 5.7) vs (16.1 +/- 5.0) micromol/L (t = 4.19, P < 0.01), serum ferritin was (94.9 +/- 76.4) vs (116.6 +/- 85.2) microg/L (t = 2.58, P < 0.01), saturation of transferrin was 22.9% +/- 10.0% vs 25.6% +/- 8.7% (t = 3.16, P < 0.01), respectively. Multifactor conditioned logistic regression analysis showed that the odd ratio (OR) for anemia with annual income, whether experiencing food scarce period, daily average physical active time, staple food, soybean products, energy was 0.57, 4.74, 0.06, 0.59, 0.55, 0.65, respectively; their confidence interval (CI) was 0.45 - 0.71, 0.73 - 30.56, 0.01 - 0.52, 0.38 - 0.91, 0.34 - 0.87, 0.44 - 0.98, respectively., Conclusion: The quality of diet, health status and related blood indexes in anemia elderly women were lower than those in control group; lower income, less active time, less staple food, soybean products and energy intake should be risk factors of anemia.
