This study aimed to prove what factors influence fathers' involvement in early childhood care. The design of this research was cross-sectional. The population was fathers having the child aged from one month to six years in Bukittinggi. The samples comprised 92 respondents selected through purposive sampling. The independent variables were age at first becoming a father, father's occupation, mother's occupation, father-mother relationship, number of children, father's willingness to be involved, place of residence, and caregiver assistance, while the dependent variable was father's involvement. Data collection used a questionnaire, and the data were analyzed using Spearman's Rho with < 0.05. The results showed that the number of children (OR = 11,449, 95%CI = 3,596-36,444) influenced the father's involvement in early childhood care with a probability value of 46.7%. The age of first fatherhood, father's occupation, mother's occupation, number of children, place of residence, and help of caregivers determine the father's involvement in raising the children. The novelty of this research is that health workers need to develop education for families in early childhood care. It is recommended to increase the father's involvement in childcare by increasing the first age of becoming a father to the age of more than 27 years, increasing the willingness of fathers to be involved in childcare, and choosing a place to live separately from parents or in-laws.

Stunting, wasting and being underweight are some of the significant health issues observed in Indonesia. A program called Community-Based Nutrition Recording and Reporting (e-PPGBM) is used to identify the prevalence of child malnutrition. This study aimed to use the e-PPGBM tool to examine the variables that affect toddlers’ stunting, wasting, and underweight due to malnutrition. This study used cross-sectional research and quantitative analysis as its methodology. Using total sampling, 574 respondents were chosen as the samples, with the appropriate details: 316 people had stunting, 191 had wasting, and 67 had underweight. The findings of this study revealed a correlation of the occurrence of stunting with the exposure to cigarettes (26.6%), basic immunization (86.1%), helminthiasis (61.1%), and clean water facilities (4.7%), as well as the occurrence of wasting with the exposure to cigarettes (79.1%), incomplete basic immunization (26.7%), helminthiasis (6.8 %), and a lack of clean water facilities (12.6%). However, there was no statistically significant factor linked to the occurrence of underweight. As a result, this study recommends using a multi-strategy approach to address the root causes and immediate problems of under-five malnutrition.
