ABSTRACT
BACKGROUND: Newborn oil massage is a widespread practice. Vigorous massage with potentially harmful products and forced removal of vernix may disrupt skin barrier integrity. Hospitalized, very preterm infants treated with sunflower seed oil (SSO) have demonstrated improved growth but community-based data on growth and health outcomes are lacking.
OBJECTIVE: We aimed to test whether SSO therapy enhances neonatal growth and reduces morbidity at population-level.
DESIGN: We conducted an open-label, controlled trial in rural Uttar Pradesh, India, randomly allocating 276 village clusters equally to comparison (usual care) and intervention comprised of promotion of improved massage practices exclusively with SSO, using intention-to-treat and per-protocol mixed-effects regression analysis.
RESULTS: We enrolled 13,478 and 13,109 newborn infants in demographically similar intervention and comparison arms, respectively. Adherence to exclusive SSO increased from 22.6% of intervention infants enrolled in the first study quartile to 37.2% in the last quartile. Intervention infants gained significantly more weight by 0.94 grams/kilogram/day (g/kg/d) [95% confidence interval (CI): 0.07, 1.82, p = 0.03] than comparison infants by intention-to-treat analysis. Restricted cubic spline regression revealed the largest benefits in weight gain (2-4 g/kg/day) occurred in infants <2000 g. Weight gain in intervention infants was higher by 1.31 g/kg/d (95% CI: 0.17, 2.46, p = 0.02) by per-protocol analysis. Morbidities were similar by intention-to-treat analysis but in per-protocol analysis rates of hospitalization and of any illness were reduced by 36% [odds ratio (OR): 0.64; 95% CI: 0.44, 0.94, p = 0.02] and 44% (OR: 0.56; 95% CI: 0.40, 0.77, p<0.001), respectively, in treated infants.
CONCLUSIONS: SSO therapy improved neonatal growth, and reduced morbidities when applied exclusively, across the facility-community continuum of care at population-level. Further research is needed to improve demand for recommended therapy inside hospital as well as in community settings, and to confirm these results in other settings. Clinical Trial Registry: The trial was registered at the ISRCTN (ISRCTN38965585) and CTRI (CTRI/2014/12/005282) registries with WHO UTN # U1111-1158-4665.
