To evaluate the effectiveness of a radio campaign involving serial 10-minute drama episodes, 10-minute on air discussion of each episode by trained community health workers and 30-minute phone-ins from listeners in improving mothers' nutrition- and health-related attitudes (HNRAs) and children's minimum acceptable diet (MAD).
A two-arm quasi-experimental trial with a pre-post design was used to quantify the effect of a radio campaign on nutrition before and immediately after the 6-month intervention. Difference-in-difference (DID) analysis was performed to assess the intervention's effect.
Saboba district (intervention) and Central Gonja (comparison district) of northern region of Ghana.
At baseline, a total of 598 mothers with children aged 6-22 months were randomly selected from the intervention ( 298) and control ( 300) districts. At endline (6 months post-intervention), 252 mother-child dyads in the intervention district and 275 mother-child dyads in the control district were followed up.
The radio campaign was significantly and positively associated with a change in health- and nutrition-related attitudes (HNRA) over time, with DID in mean attitudes significantly improving more over time in the intervention district than the control (DID = 1·398, < 0·001). Also, the prevalence of MAD over time in the intervention district was significantly higher than the control district (DID = 16·1 percentage points, = 0·02) in the presence of food insecurity.
The study indicates that a radio campaign on nutrition is associated with improved mothers' HNRA and children's MAD. Communication interventions on child nutrition targeting low-resource settings should consider this innovative approach.
评估一个广播宣传活动的效果，该活动包括连续 10 分钟的戏剧剧集、由经过培训的社区卫生工作者对每集进行 10 分钟的空中讨论以及听众进行 30 分钟的电话参与，以改善母亲的营养和健康相关态度（HNRAs）和儿童的最低可接受饮食（MAD）。
采用前后设计的双臂准实验试验来量化营养干预前和 6 个月干预后广播宣传活动对营养的影响。采用差异（DID）分析来评估干预的效果。
加纳北部地区的萨博巴区（干预区）和中央贡贾区（对照区）。
在基线时，从干预区（298 名）和对照区（300 名）中随机选择了总共 598 名年龄在 6-22 个月的母亲及其子女。在终点（干预后 6 个月），对干预区的 252 对母婴和对照区的 275 对母婴进行了随访。
广播宣传活动与健康和营养相关态度（HNRAs）随时间的变化显著且呈正相关，干预区的平均态度随时间的 DID 显著改善大于对照组（DID = 1·398， < 0·001）。此外，在存在粮食不安全的情况下，干预区的 MAD 随时间的流行率显著高于对照组（DID = 16·1 个百分点， = 0·02）。
该研究表明，营养广播宣传活动与母亲 HNRAs 和儿童 MAD 的改善有关。针对资源匮乏环境的儿童营养传播干预措施应考虑这种创新方法。
