Home environment influences child health, but the impact varies as children move into adolescence. The Family Nutrition and Physical Activity (FNPA) screening tool has been used to evaluate home environments, but studies have not compared the utility of the tool in different age groups. The purpose of this study was to examine the efficacy of the FNPA tool in first and tenth grade samples. Parents of first grade ( = 250) and tenth grade ( = 99) students completed the FNPA and results were linked to body mass index (BMI) data. FNPA scores were examined by gender, income, race, and school-level socioeconomic status (SES). Correlations examined associations between FNPA scores and several BMI indicators. Logistic and linear regression analyses evaluated the construct validity of the FNPA in both groups. Mean FNPA score differed by age group, by SES in both age groups, and by race in the first grade sample only. Correlations between FNPA score and BMI indicators were higher in the first grade sample, but SES was significantly associated with BMI only in tenth graders. The FNPA has stronger utility in younger children, while school SES is a stronger predictor of adolescent weight status.
家庭环境会影响儿童健康，但随着儿童步入青春期，这种影响会有所不同。家庭营养与身体活动（FNPA）筛查工具已被用于评估家庭环境，但此前的研究并未比较该工具在不同年龄组中的效用。本研究的目的是检验FNPA工具在一年级和十年级样本中的有效性。一年级（n = 250）和十年级（n = 99）学生的家长完成了FNPA评估，结果与体重指数（BMI）数据相关联。FNPA得分按性别、收入、种族和学校层面的社会经济地位（SES）进行了分析。相关性分析考察了FNPA得分与多个BMI指标之间的关联。逻辑回归和线性回归分析评估了FNPA在两组中的结构效度。平均FNPA得分在不同年龄组、两个年龄组的SES以及仅一年级样本中的种族之间存在差异。一年级样本中FNPA得分与BMI指标之间的相关性更高，但只有十年级学生的SES与BMI显著相关。FNPA在年幼儿童中效用更强，而学校SES是青少年体重状况的更强预测指标。
