To determine if fruit and vegetable consumption among high- and low-socioeconomic status (HSES-LSES) urban schoolchildren in Quetzaltenango, Guatemala, was adequate according to World Health Organization (WHO) recommendations.
Cross-sectional data from 449 third- and fourth-grade girls and boys from 12 elementary schools were collected, analyzed, and presented by socioeconomic status and gender. Public schoolchildren were classified as LSES (n = 219) and private schoolchildren were classified as HSES (n = 230). Dietary fruit/vegetable intake of each student was determined based on a 24-hour recall pictorial record and personal interview. All food items containing fruits or vegetables (including beverages) were classified and tabulated. Frequency of fruit/vegetable intake was calculated based on "mentions" (number of times a fruit or vegetable item was reportedly consumed), and nutritional adequacy was assessed for each group by mean and median values and compared to WHO daily recommended fruit/vegetable intake (400 g). Based on World Cancer Research Fund (WCRF) exclusion guidelines, the fruit/vegetable contribution to total energy was estimated.
Of the 247 different food items identified, 93 (37.7%) contained a fruit or vegetable. Total food mentions (n = 6 512) included 637 fruit items and 701 vegetable items. Although mean fruit/vegetable intake in grams was 461.3 (standard deviation, +/- 332.5), more than half (56.3%) of the subjects fell below the 400-g recommended daily level. Estimated fruit/vegetable contribution to total energy was 21.2% for HSES and 19.1% for LSES.
This study revealed inadequate fruit/vegetable intake among the study sample. For compliance with global recommendations, interventions promoting fruit/vegetable intake are needed.
根据世界卫生组织(WHO)的建议,确定危地马拉克萨尔特南戈市社会经济地位高-低(HSES-LSES)的城市学童的水果和蔬菜摄入量是否充足。
收集了来自12所小学的449名三、四年级男女生的横断面数据,并按社会经济地位和性别进行分析和呈现。公立学校的学童被归类为低社会经济地位(n = 219),私立学校的学童被归类为高社会经济地位(n = 230)。根据24小时回忆图片记录和个人访谈确定每个学生的膳食水果/蔬菜摄入量。对所有含有水果或蔬菜的食品(包括饮料)进行分类和制表。根据“提及次数”(据报道食用水果或蔬菜项目的次数)计算水果/蔬菜摄入频率,并通过均值和中位数评估每组的营养充足性,并与WHO每日推荐的水果/蔬菜摄入量(400克)进行比较。根据世界癌症研究基金会(WCRF)的排除指南,估计水果/蔬菜对总能量的贡献。
在确定的247种不同食品中,93种(37.7%)含有水果或蔬菜。食品提及总数(n = 6512)包括637个水果项目和701个蔬菜项目。虽然水果/蔬菜摄入量的平均克数为461.3(标准差,+/- 332.5),但超过一半(56.3%)的受试者低于每日400克的推荐水平。高社会经济地位组水果/蔬菜对总能量的估计贡献为21.2%,低社会经济地位组为19.1%。
本研究表明研究样本中的水果/蔬菜摄入量不足。为了符合全球建议,需要采取促进水果/蔬菜摄入的干预措施。
