中年体能(PC)与经济发达国家人口的发展因素有关。据我们所知,没有低收入和中等收入国家农村人口的信息。该研究的目的是在来自墨西哥农村社区的1966-67出生队列中,调查产前和产后因素对中年PC客观指标的影响。假设是不利的发育条件与中年PC低有关。
在1966-67年,来自墨西哥贫困农村社区的所有儿童的出生队列被组装。关于家庭社会经济地位(SES)的数据,父母的健康状况和营养状况,出生体重,记录了出生后的生长和喂养方式。2018年,在336名队列成员中,118人住在社区里,其中82例接受了全面的临床评估。评估包括握力,步态速度和椅架PC测试。在多变量线性模型中,PC测试是因变量,产前,出生和出生后因素是自变量.用成人人体测量学对混杂因素进行了调整,身体成分,临床和衰老状态变量。
与成人健康状况和其他老龄化指标无关,较低的PC与家庭组织和SES有关,父母的营养状况,出生体重,婴儿出生后生长速度,断奶时间。这些结果表明,贫困农村社区普遍存在的不利家庭和环境条件与中年PC低有关。
Midlife physical capability (PC) is associated with developmental factors in the populations of economically developed countries. As far as we know, there is no information for rural populations of low- and middle-income countries. The aim of the study was to investigate the influence of pre- and postnatal factors on midlife objective measures of PC in a 1966-67 birth cohort from a Mexican rural community. The hypothesis was that adverse developmental conditions are associated with low midlife PC.
In 1966-67, a birth cohort of all children from a poor Mexican rural community was assembled. Data on family socioeconomic status (SES), parental health and nutritional status, birth weight, postnatal growth and feeding patterns were registered. In 2018, out of the 336 cohort members, 118 were living in the community, and eighty-two of them underwent a comprehensive clinical evaluation. The evaluation included grip strength, gait velocity and chair-stand PC tests. In multivariable linear models, PC tests were the dependent variables, and prenatal, birth and postnatal factors were the independent variables. Adjustment for confounding was made with adult anthropometric, body composition, clinical and ageing status variables.
Independent of adult health status and other ageing indicators, lower PC was associated with family organization and SES, parental nutritional status, birth weight, infant postnatal growth velocity, and weaning time. These results indicate that adverse family and environmental conditions that are prevalent in poor rural communities are associated with low midlife PC.
