To assess the relationship between programme attendance in a produce prescription (PRx) programme and changes in cardiovascular risk factors.
The Georgia Food for Health (GF4H) programme provided six monthly nutrition education sessions, six weekly cooking classes and weekly produce vouchers. Participants became programme graduates attending at least 4 of the 6 of both the weekly cooking classes and monthly education sessions. We used a longitudinal, single-arm approach to estimate the association between the number of monthly programme visits attended and changes in health indicators.
GF4H was implemented in partnership with a large safety-net health system in Atlanta, GA.
Three hundred thirty-one participants living with or at-risk of chronic disease and food insecurity were recruited from primary care clinics. Over three years, 282 participants graduated from the programme.
After adjusting for programme site, year, participant sex, age, race and ethnicity, Supplemental Nutrition Assistance Program participation and household size, we estimated that each additional programme visit attended beyond four visits was associated with a 0·06 kg/m reduction in BMI (95 % CI -0·12, -0·01; = 0·02), a 0·37 inch reduction in waist circumference (95 % CI -0·48, -0·27; < 0·001), a 1·01 mmHg reduction in systolic blood pressure (95 % CI -1·45, -0·57; < 0·001) and a 0·43 mmHg reduction in diastolic blood pressure (95 % CI -0·69, -0·17; = 0·001).
Each additional cooking and nutrition education visit attended beyond the graduation threshold was associated with modest but significant improvements in CVD risk factors, suggesting that increased engagement in educational components of a PRx programme improves health outcomes.
评估参与农产品处方（PRx）计划与心血管风险因素变化之间的关系。
佐治亚州食品与健康（GF4H）计划提供了六次每月营养教育课程、六次每周烹饪课程和每周农产品代金券。参与者成为计划毕业生，至少参加了 6 次每周烹饪课程和每月教育课程中的 4 次。我们采用纵向、单臂方法来估计每月参加计划的次数与健康指标变化之间的关联。
GF4H 是与佐治亚州亚特兰大的一家大型医疗保障系统合作实施的。
从初级保健诊所招募了 331 名患有慢性疾病或处于慢性病风险中且存在粮食不安全问题的参与者。在三年期间，有 282 名参与者从该计划毕业。
在校正计划地点、年份、参与者性别、年龄、种族和民族、补充营养援助计划参与情况和家庭规模后，我们估计，除了四次访问之外，每次额外参加计划访问与 BMI 降低 0.06kg/m（95%CI -0.12, -0.01； = 0.02）、腰围减少 0.37 英寸（95%CI -0.48, -0.27；<0.001）、收缩压降低 1.01mmHg（95%CI -1.45, -0.57；<0.001）和舒张压降低 0.43mmHg（95%CI -0.69, -0.17； = 0.001）相关。
除了毕业门槛之外，每次额外参加烹饪和营养教育访问都与 CVD 风险因素的适度但显著改善相关，这表明增加参与 PRx 计划的教育部分可以改善健康结果。
