To construct a growth curve for children aged 6-12 years residing in Zhuzhou, assess the height distribution among local elementary school students, and analyze the factors contributing to short stature.
We measured the heights of children from 110 elementary schools in Zhuzhou using cluster sampling. A total of 106,864 samples of children aged 6-12 years were collected and divided into 25 age groups, each spanning three months. The Lambda-Mu-Sigma (LMS) method was employed to calculate the 3rd, 10th, 25th, 50th, 75th, 90th, and 97th percentiles of height for each age group. Children below the 3rd percentile according to the national growth curve made in 2005 were considered to be short stature. The heights of boys and girls in Zhuzhou were compared with the national average heights from 2005. The height growth curve was constructed using the curve estimation function of SPSS software and the influencing factors for the prevalence of short stature were identified using logistic regression analysis based on data obtained from parental questionnaires.
The prevalence of short stature among children aged 6-12 years in Zhuzhou was found to be 3.97%. Boys exhibited a significantly higher incidence of short stature at 4.53% compared to girls at 3.37%. Children residing in suburban areas showed a notably higher prevalence of short stature (5.80%) compared to their urban counterparts (3.67%), with these disparities proving statistically significant. Logistic regression analysis identified several contributing factors for short stature in this population, including low birth weight, inadequate daily physical activity (less than 0.5 h), father's educational qualification of junior college level or below, short stature of parents, insufficient sleep duration, and male gender.
To improve children's height in Zhuzhou, it's important for them to exercise for over 30 min daily and sleep for more than 10 h each night. Regular monitoring of growth and nutrition is crucial. Health education for families with less educated fathers and early intervention for children with short-statured parents are also key strategies.
构建株洲市6至12岁儿童的生长曲线，评估当地小学生的身高分布情况，并分析导致身材矮小的因素。
我们采用整群抽样法测量了株洲市110所小学儿童的身高。共收集了106,864例6至12岁儿童的样本，并将其分为25个年龄组，每组跨度为三个月。采用Lambda-Mu-Sigma（LMS）方法计算每个年龄组身高的第3、10、25、50、75、90和97百分位数。根据2005年制定的全国生长曲线，身高低于第3百分位数的儿童被视为身材矮小。将株洲市男、女童的身高与2005年全国平均身高进行比较。使用SPSS软件的曲线估计功能构建身高生长曲线，并基于家长问卷获得的数据，采用逻辑回归分析确定身材矮小患病率的影响因素。
发现株洲市6至12岁儿童身材矮小的患病率为3.97%。男孩身材矮小的发生率显著高于女孩，分别为4.53%和3.37%。与城市儿童（3.67%）相比，郊区儿童身材矮小的患病率明显更高（5.80%），这些差异具有统计学意义。逻辑回归分析确定了该人群身材矮小的几个影响因素，包括低出生体重、每日体育活动不足（少于0.5小时）、父亲大专及以下学历、父母身材矮小、睡眠时间不足以及男性性别。
为提高株洲市儿童的身高，他们每天进行超过30分钟的运动和每晚睡眠超过10小时很重要。定期监测生长和营养状况至关重要。对父亲受教育程度较低的家庭进行健康教育以及对父母身材矮小的儿童进行早期干预也是关键策略。
