摘要:目的 研究中國青春前期女童鈣代謝狀況,了解中國青春 前期女童鈣吸收率和影響鈣吸收率的因素。 方法 選擇 49 名處于生長(cháng)突增期、未月經(jīng)初潮的青春前期女童,采用經(jīng)典鈣代謝實(shí)驗方法,在 600 ~ 1500mg/d 范圍內設計 4 個(gè)不同的鈣攝入劑量組,觀(guān)察研究對象的鈣代謝狀況。結果 在 600 ~ 1500mg/d 鈣攝入量范圍內,各組對象鈣表觀(guān)鈣吸收率未發(fā)現差別,平均吸收率為 (53 ± 0 . 12)%( 范圍 52% ~ 55%) 。膳食蛋白質(zhì)水平與鈣吸收率、糞鈣量無(wú)相關(guān)關(guān)系,尿鈣與膳食磷含量、蛋白質(zhì)含量顯著(zhù)負相關(guān) (P<0 . 01) 。 結論 中國青春前期女童鈣的表觀(guān)吸收率為 53 %;高膳食蛋白質(zhì)能增加尿鈣的排出。

Abstract : Objective\ To investigate the characteristics of calcium metabolism in relation to different levels of dietary calcium intakes in premenarche Chinese girls. Methods Forty - nine healthy premenarche girls of Han ethic (9-11 . 5 years) were recruited, and divided into four groups respectively, receiving four differe nt doses of calcium intakes for 6 days, 600 mg (usual diet), 900 mg (containing 250ml of milk), 1200 mg (containing 250ml of milk and 750 mg of calcium carbonate) and 1500mg calcium (250ml of milk and 1500 mg of calcium carbonate) per day. A 3 day urine and stool, and a 3 d duplicated food samples were collected to assess the calcium excretion in urine and feces and input of the dietary calcium during the treatment period. Results There were no significant differences in appearance calcium absorption among the four groups (55%, 53%, 52% and 52%). Urine calcium is correlated negatively with dietary protein and dietary phosphorus. And no correlation was found between dietary protein and calcium absorption. Conclusion The appearance calcium absorption was (53 ± 0 . 12)% in Chinese premenarche girls with dietary calcium intakes ranged between 800 to 1600 mg/d, high dietary protein intakes increase urine calcium secrete.

摘要:目的 了解中老年人三種常見(jiàn)慢性病 ( 高脂血癥、高血壓、糖尿病 ) 的患病狀況,探明這些疾病的主要危險因素,找出社區慢病防治途徑和方法。 方法 對隨機抽取的 2120 名 45 歲以上的中老年居民進(jìn)行體格檢查和問(wèn)卷調查。采用 1 ∶ 1 配對病例對照研究,對 19 個(gè)因素進(jìn)行單因素非條件 Logistic 回歸分析和多因素非條件 Logistic 回歸分析篩選出有意義的因素。結果 高脂血癥、高血壓和糖尿病的檢出率經(jīng)標化后分別是 50 . 12% 、 44 . 26% 和 8 . 74% ,與高脂血癥相關(guān)的因素有 7 個(gè),其中主要因素有人均月收入、體質(zhì)指數 (BMI) 分級、腹型肥胖和粗糧攝入;與高血壓相關(guān)的因素有 11 個(gè),其中主要因素有年齡、吸煙、緊張程度、 BMI 分級和腹型肥胖;與糖尿病密切相關(guān)的因素有 5 個(gè):家族史、 BMI 分級、腹型肥胖、粗糧攝入和體育鍛煉。 結論 肥胖和不良的生活行為方式是三種慢性病患病的主要危險因素,粗糧攝入和體育鍛煉是主要的保護因素,增強保護因素和減少危險因素是社區慢性病防治的關(guān)鍵措施。

Abstract : Objective To find out the prevalence of hyperlipemia, hypertension and diabetes, and explore the primary influence factors. Methods The survey consists of questionnaire and health examination on 2120 elderly adults aged above 45 year old. The possible influence factors and the primary factors in 19 factors were analyzed and screened by case - control study and logistic regression analysis. Results This investigation showed that the prevalence rates of hyperlipemia, hypertension, and diabetes were 50 . 12%,44 . 26% and 8 . 74% respectively. For hyperlipemia: monthly income, BMI, WHR, coarse food grain were primary factors. For hypertension: age, smoke, intensity, BMI, WHR were primary factors. For diabetes: family history of disease, BMI,WHR, coarse food grain, exercises were primary factors. Conclusion The risk factors of the three chronic diseases were obesity and unhealthy life styles, and the protective factors were coarse food grian and exercises. It's important to decrease prevalence of chronic diseases in community by controlling these risk factors. Key words:chronic diseases, influence factor, elderly adults
