Factors Influencing Growth of Children Aged 12-24 Months in the Tanga Region, Tanzania.

BACKGROUND

The first 1000 days of life, from conception to the second birthday, offer a unique window of opportunity for optimal growth, critical for future health. The primary aim of this study was to analyze growth of children between 12 and 24 months age in Tanzanian children, and to explore possible predictors for growth.

METHODS

Observational, cross-sectional study performed between March and April 2017. Eligible children, and their mothers, attended routine follow-up at two health clinics in Tanga, Tanzania. At the study day, the child's weight and height were recorded. The mothers answered a structured interview regarding breastfeeding, immunization and socioeconomic conditions.

RESULTS

We recruited 300 mother-child pairs. Median [interquartile range (IQR)] age at study visit was 16 (14-20) months. Mothers reported that 170 (57%) of their children were exclusively breastfed for a minimum of 6 months; median (IQR) 6 (4-6) months. Using the World Health Organization (WHO) standard growth curves, mean weight-for-age Z-score was -0.30 and mean length-for-age Z-score was -0.47. Children whose mothers had higher education had higher Z-scores for weight and length compared to children of mothers with lower education. Education remained the most important predictor for growth also after adjusting for other variables. Overall, 48/300 (16%) were moderate-severe stunted and 25/300 (8.4%) had moderate-severe underweight.

CONCLUSION

Children aged 12-24 months in this region of Tanzania had weight and height below the WHO standard. Higher educated mothers had children with better growth parameters. Duration of exclusive breastfeeding was long, but did not predict growth parameters.
