<b>LINEAR PROGRAMMED DIETARY PLAN DATASET </b><b>ON IMPROVING ENERGY INTAKE AMONG CHILDREN LIVING WITH HIV AGED 2-5 YEARS</b>Nutrition Education Intervention Dataset on Improving Caregivers Knowledge, attitude and Energy Intake Among Children Aged 2-5 years Living with HIV in Simiyu region, Tanzania

Most children living with HIV have decreased energy intake due to loss of appetite, which results in weight loss. The diets of many children living with HIV do not meet the recommended levels of energy intake. This study dataset was collected to test the effectiveness of a linear programmed dietary plan in improving the energy intake of children living with HIV aged 2-5 years in the Simiyu region in Tanzania.The study dataset was from a cluster randomized control trial designed with both intervention and control arms and used a quantitative approach. Care and treatment center (CTCs) was the unit of randomization. The study involved 200 asymptomatic children living with HIV aged 2 – 5 years. The linear programmed dietary plans were developed with 1390 Kcals. The linear programmed dietary plan education was provided to the intervention group. Questionnaires were used to measure nutrition knowledge and attitude. Repeated measures of ANOVA were used to analyze the data.There was a significant increase in mean knowledge change (mean change) =2.48(95%CI=1.5-3.3), P=&lt;0.01) as a result of an intervention (F=5.1; P=0.025) with an effect size of (Cohen’s d=0.5{95%CI=0.21-0.78}.The mean change for attitude was 8.49{95%CI=7.02-9.96}, P=&lt;0.001 with significant strength of the intervention F=48.9; P=0.001) with effect size (Cohen’s d =1.2{95%CI=0.87-1.48}.The mean change for energy intake was 351.82(95%CI =303.20-400.44}, P=&lt;0.001) with significant strength of the intervention F=57.95; P=0.001) and effect size (Cohen’s d=1.5(1.29-1.73)The intervention effectively increased knowledge and changed attitudes, increasing energy intake among this population.

多数艾滋病病毒（HIV）感染儿童会因食欲减退出现能量摄入不足，进而引发体重下降。诸多HIV感染儿童的膳食能量摄入未达到推荐标准。本研究数据集旨在验证线性规划膳食方案对坦桑尼亚西米育（Simiyu）地区2-5岁HIV感染儿童能量摄入的改善效果。
本数据集来源于一项设有干预组与对照组的整群随机对照试验，研究采用定量研究方法，以护理与治疗中心（Care and Treatment Center, CTCs）作为随机分组单位。本研究共纳入200名2-5岁无症状HIV感染儿童。本次研究的线性规划膳食方案热量设定为1390千卡，干预组接受了该膳食方案的相关教育。研究采用问卷法评估受试者的营养知识与态度水平，数据分析采用重复测量方差分析（Repeated Measures ANOVA）方法。
干预后，受试者的营养知识平均得分变化量为2.48（95%置信区间CI=1.5~3.3），P≤0.01；干预效应显著（F=5.1，P=0.025），效应量科恩d值（Cohen’s d）=0.5（95%CI=0.21~0.78）。态度量表得分平均变化量为8.49（95%CI=7.02~9.96），P≤0.001；干预效应显著（F=48.9，P=0.001），效应量Cohen’s d=1.2（95%CI=0.87~1.48）。能量摄入平均变化量为351.82（95%CI=303.20~400.44），P≤0.001；干预效应显著（F=57.95，P=0.001），效应量Cohen’s d=1.5（95%CI=1.29~1.73）。本研究表明，该干预方案可有效提升该群体的营养知识水平、改善其膳食态度，并增加能量摄入。
