Increased intakes of ready-made and fast foods paralleled with decreased homemade food consumption have been associated with increased rates of obesity. Researchers have shown associations between cooking self-efficacy (SE) and cooking frequency (CF) with dietary quality and weight status. Some cooking interventions have shown positive associations with dietary outcomes, such as increased fruit and vegetable intake and decreased fast food consumption. There is still much unknown about SE and CF, especially among youth.
Determine baseline SE and CF and the associations with dietary quality and body mass index (BMI) of youth enrolled in iCook 4H.
Youth (n = 228, ages 9-10 years) completed online surveys assessing SE, CF, dietary quality, and demographics. Anthropometrics were collected to calculate BMI-for-age percentiles and weight categories. Descriptive statistics were completed for CF, SE, BMI categories, and demographics. Differences in CF and SE by sex, race, and participation in government assistance programs were determined through independent-sample tests. Pearson correlations were used to assess the association between dietary quality and CF and SE. Associations between CF and dietary quality were assessed further through 2-way analyses of variance (ANOVAs) that included CF and sex and CF and race as independent variables. Associations between SE and CF and BMI were assessed through ANOVAs.
Thirty-seven percent of youth were overweight or obese. Females reported significantly higher CF than males ( = .042). Cooking frequency was positively associated with dietary quality ( < .001), but BMI was not associated with dietary quality. SE was not associated with dietary quality or BMI.
Based on results, CF was positively associated with dietary quality among youth. More research is needed to assess how different types of cooking relate to diet and BMI. Interventions are needed to determine whether increasing CF leads to better diet outcomes.
预制食品和快餐摄入量的增加以及家庭自制食品消费量的减少与肥胖率上升有关。研究人员已经表明烹饪自我效能感(SE)和烹饪频率(CF)与饮食质量和体重状况之间存在关联。一些烹饪干预措施已显示出与饮食结果的积极关联,如水果和蔬菜摄入量增加以及快餐消费量减少。关于SE和CF仍有许多未知之处,尤其是在青少年中。
确定参加iCook 4H项目的青少年的基线SE和CF,以及它们与饮食质量和体重指数(BMI)的关联。
青少年(n = 228,年龄9至10岁)完成了在线调查,评估SE、CF、饮食质量和人口统计学特征。收集人体测量数据以计算年龄别BMI百分位数和体重类别。对CF、SE、BMI类别和人口统计学特征进行描述性统计。通过独立样本t检验确定性别、种族和参与政府援助项目对CF和SE的差异。使用Pearson相关性来评估饮食质量与CF和SE之间的关联。通过双向方差分析(ANOVA)进一步评估CF与饮食质量之间的关联,其中将CF和性别以及CF和种族作为自变量。通过ANOVA评估SE和CF与BMI之间的关联。
37%的青少年超重或肥胖。女性报告的CF显著高于男性(P = 0.042)。烹饪频率与饮食质量呈正相关(P < 0.001),但BMI与饮食质量无关。SE与饮食质量或BMI均无关。
基于结果,CF与青少年的饮食质量呈正相关。需要更多研究来评估不同类型的烹饪与饮食和BMI之间的关系。需要进行干预以确定增加CF是否会带来更好的饮食结果。
