Few studies have considered the combined effects of home-related determinants on children’s diet. The present study investigated independent associations between sociodemographic and food practice (SFP) characteristics and fruit and vegetable consumption in U.K. children and the combined effects of SFP on consumption using pattern analysis.
Diet was assessed using 4 d food diaries, SFP were collected using computer-assisted personal interview. Linear regressions were used to test associations; principal component analysis was used to identify patterns of SFP characteristics. Regression of fruit (g/d) and vegetables (g/d) v. component scores of each pattern were performed.
U.K. National Diet and Nutrition Survey Rolling Programme (2008–2010).
Children aged 1.5–10 years (n 642).
Significant associations were found between fruit and vegetable consumption and household socio-economic status. Pattern 1, which was positively correlated with household structure characteristics, was associated with increased fruit consumption (P < 0.001). Pattern 2, characterised by positive correlations for socio-economic status, fruit availability and organic food purchase, and negatively correlated with household size and the number of children per household, was associated with higher fruit and vegetable consumption (both P < 0.001). Pattern 3, characterised by high frequency of eating out and eating takeaway, was associated with a lower consumption of both fruit (P < 0.012) and vegetables (P < 0.023).
Patterns of SFP determinants may be more informative than individual characteristics in relation to dietary outcomes. Results have public health implications on the healthfulness of meals eaten out of home and in takeaways, as well as the need to reduce diet inequality in larger households with lower socio-economic status.
很少有研究考虑家庭相关决定因素对儿童饮食的综合影响。本研究调查了英国儿童社会人口学和饮食实践（SFP）特征与水果和蔬菜消费之间的独立关联，以及使用模式分析对消费的 SFP 综合影响。
饮食使用 4 天食物日记进行评估，SFP 使用计算机辅助个人访谈收集。线性回归用于测试关联；主成分分析用于识别 SFP 特征的模式。对每种模式的水果（g/d）和蔬菜（g/d）的回归与成分得分进行了回归分析。
英国国家饮食与营养调查滚动计划（2008-2010 年）。
年龄在 1.5-10 岁的儿童（n=642）。
发现水果和蔬菜消费与家庭社会经济地位之间存在显著关联。与家庭结构特征呈正相关的模式 1 与增加水果消费相关（P<0.001）。模式 2 以社会经济地位、水果供应和有机食品购买呈正相关，家庭规模和每户儿童数量呈负相关为特征，与更高的水果和蔬菜消费相关（均 P<0.001）。模式 3 以外出就餐和外卖用餐频率高为特征，与水果（P<0.012）和蔬菜（P<0.023）的消费均较低相关。
SFP 决定因素的模式可能比个体特征更能反映饮食结果。这些结果对在外出就餐和外卖用餐时的饮食健康以及减少社会经济地位较低的大家庭中的饮食不平等问题具有公共卫生意义。
