Food aid provision associated with reduced anxiety and insomnia symptoms in food-insecure Pakistani adults
This exploratory randomized controlled trial enrolled 186 participants from food aid distribution centers in Pakistan to examine the effects of food aid provision on psychological outcomes. Participants were assigned to either receive food aid or serve as waitlist controls. The study did not report a primary outcome, follow-up duration, or safety data.
Food aid provision was associated with significantly lower anxiety scores compared to waitlist control (mean 2.71 vs. 3.83, p < .001, Cohen's d = -1.57). Insomnia symptoms were also significantly lower in the food aid group (mean 2.66 vs. 3.28, p < .001, Cohen's d = -0.57). A mediation analysis suggested anxiety reduction accounted for part of the effect on insomnia symptoms (indirect effect estimate = -0.45, 95% CI [-0.23, -0.69]).
No safety, adverse event, or tolerability data were reported. The study did not specify funding sources or conflicts of interest. Key limitations include the exploratory design, absence of safety monitoring, lack of follow-up duration reporting, and conduct in a specific high-food-insecurity context that may limit generalizability.
While these findings suggest food aid may address insomnia in contexts where traditional therapeutic approaches are impractical to scale, clinicians should interpret them cautiously. The evidence remains preliminary, and the study does not establish whether effects persist beyond the intervention period or apply to other populations.
