摘要
背景:研究证明绝经后骨质疏松症与女性生殖特点和运动膳食有关,但是鲜有研究证明女性生殖特点及运动膳食是否对绝经后女性维生素D有影响。目的:探讨北京市绝经后女性维生素D水平与女性生殖特点和运动膳食情况的关系及其影响因素。方法:选取2017年9月至2018年5月北京市多个城区的17个社区现场问卷调查的727例46-75岁绝经后女性作为研究对象,问卷内容包括受试者的基本信息和月经史、绝经史、妊娠史、运动膳食情况等。采用电化学发光免疫分析仪及其配套试剂测定25-(OH)D水平;使用双能X射线骨密度检测仪测定腰椎(L1-L4、整体)和双髋关节(股骨颈、整体)的骨密度和T值;观察维生素D与生殖特点和运动膳食的相关性,并进行维生素D的影响因素分析。结果与结论:①维生素D正常组136例(18.7%),维生素D不足组389例(53.5%),维生素D缺乏组202例(27.8%);平均维生素D水平为(15.60±5.85)ng/mL。②随着维生素D水平的升高,不同部位的骨密度值及T值也随之升高。③维生素D水平与初潮年龄、月经持续天数、绝经阶段、运动情况、饮食类型、饮食偏好均呈正相关(P<0.05);与月经周期、绝经年龄、生育次数均呈负相关(P<0.05);与初孕年龄、怀孕次数无相关性(P>0.05)。④多因素有序Logistic回归分析结果显示,喝奶制品频率对绝经后女性维生素D值存在正向相关(P<0.05),且奶制品是维生素D水平的保护因素。⑤调查结果说明,北京市绝经后女性维生素D水平普遍不足、骨密度值普遍低下,维生素D水平与部分生殖特点、运动膳食情况存在关联,且其中喝奶制品是其保护因素。因此可以通过开展相关骨质疏松的健康教育,对绝经后女性膳食情况进行调整加以干预,增加体内维生素D含量,以期增加骨密度值,减少绝经后骨质疏松患病率。
BACKGROUND:Studies have demonstrated that postmenopausal osteoporosis is related to female reproductive characteristics and exercise diets,but few studies have demonstrated whether female reproductive characteristics and exercise diets have an effect on vitamin D in postmenopausal women.OBJECTIVE:To investigate the relationship of vitamin D levels with female reproductive characteristics and exercise diets and their influencing factors in postmenopausal women in Beijing.METHODS:Totally 727 postmenopausal women with an age range of 46-75 years old who received on-site questionnaires in 17 communities of Beijing from September 2017 to May 2018 were selected as the study subjects,and the questionnaires included the subjects’basic information and history of menstruation,menopause,pregnancy,and exercise diet.An electrochemiluminescence immunoassay analyzer and its auxiliary reagents were used to determine 25-(OH)D levels.Bone mineral density and T values of the lumbar spine(L1-L4,whole)and both hips(femoral neck,whole)were determined using a dual-energy X-ray bone mineral density detector.The correlation of vitamin D with reproductive characteristics and exercise diet was observed,as well as the influencing factors of vitamin D were analyzed.RESULTS AND CONCLUSION:There were 136 cases(18.7%)in the vitamin D normal group,389 cases(53.5%)in the vitamin D insufficient group,and 202 cases(27.8%)in the vitamin D deficient group.The mean vitamin D level was(15.60±5.85)ng/mL.With the increase of vitamin D level,the bone mineral density value and T value of different parts of the body also increased.Vitamin D level was positively correlated with age at menarche,days of menstrual duration,stage of menopause,activity,diet type,and dietary preference(P<0.05);was negatively correlated with menstrual cycle,age at menopause,and number of childbearing(P<0.05);and had no correlation with age at first conception and number of pregnancies(P>0.05).The results of multifactorial ordered Logistic regression analyses showed that there wa
