Abstract
Stunting remains a major public health issue that begins early in life and is strongly
associated with inadequate maternal care, nutrition, and infant feeding practices.
Pregnant adolescents are particularly vulnerable due to limited knowledge and
readiness for childbirth and breastfeeding, which are crucial for preventing stunted
growth in infants. This quasi-experimental study aimed to evaluate the effectiveness
of a Mobile WebApp–based intervention in increasing knowledge related to childbirth
readiness and breastfeeding as part of stunting prevention among pregnant adolescents
in Narmada Subdistrict, West Lombok Regency, Indonesia. A total of 60 pregnant
adolescents who met the inclusion criteria (aged 15–19 years, first pregnancy, and
able to use smartphones) were selected using purposive sampling. The instrument, a
25-item questionnaire, was developed based on the Health Belief Model (HBM),
covering aspects of perceived susceptibility, perceived benefits, and cues to action
related to maternal and infant health. The instrument underwent expert validity testing
by three midwifery and maternal health specialists and achieved a validity coefficient
of r = 0.78 and a Cronbach’s alpha reliability value of 0.86, indicating good
consistency. The one-month Mobile WebApp intervention provided educational
modules on breast care, signs of labor, early initiation of breastfeeding (EIBF),
breastfeeding techniques, and exclusive breastfeeding up to six months of age. Data
were analyzed using the Wilcoxon signed-rank test. The results showed a significant
improvement in maternal knowledge after the intervention (p < 0.05). These findings
demonstrate that the Mobile WebApp effectively enhances pregnant adolescents’
readiness for childbirth and breastfeeding, thereby supporting efforts to prevent
stunting. Integrating mobile health applications into maternal education can strengthen
adolescent mothers’ capacity to promote optimal maternal and child health outcomes.
