Factors associated with the recovery rate of children with moderate wasting in the Far North Region of Cameroon

Background: Research on moderate acute malnutrition (MAM) is limited, despite its high prevalence. This study examined the impact of bi-weekly locally available foods provided via a Food Voucher Program (FVP) on nutritional recovery (mid-upper arm circumference (MUAC) ≥ 125 mm) from MAM (defined as MUAC between 115 and 124 mm) and identify the factors associated with recovery rate in the Far North Region of Cameroon. Methods This was a prospective study with 474 MAM children aged 6–59 months. Food voucher distribution and MUAC screening were conducted at 6 bi-weekly visits or until the child was recovered. Time-to-recovery was evaluated with multivariate Cox proportional regression hazard models with associations quantified using adjusted hazard ratio (aHR). The trend for MUAC, including its determinants, was examined with multivariate linear mixed effect models. Results The recovery rate was 78.3% by 6 weeks after the first food basket; 3.4% remained MAM, and 5.9% were transferred for treatment for SAM. Boys were 34% more likely to recover from MAM than girls (aHR = 1.34, 95%CI (1.09, 1.67)). Children aged 24–53 months were 30% more likely to recover than those aged 6–11 months (aHR = 1.30, 95%CI (0.99, 1.70)). A one unit increase in weight-for-height Z-score (WHZ) was associated with 1.89 fold greater likelihood of recovery (aHR = 1.89, 95%CI (1.66, 2.14)). Male children had on average 1.82 mm greater increase in MUAC than female children (p < 0.001). One unit increase in WHZ was associated with 3.42 mm increase in MUAC (p = 0.025). Children aged 12–23 and 24–53 months had 1.03 mm and 2.44 mm, respectively, greater increase in MUAC over the program than children aged 6–11 months (all p < 0.01). Conclusion Child’s WHZ, gender and age determined MUAC increase and recovery from MAM in the FVP. These findings indicate the approach shows promise as an effective alternative treatment for MAM with consideration of associated factors.
