Stunting is a global problem that has a long-term impact on the quality of human resources. The reduction and prevention of stunting can be carried out with supervision during the first 1000 days of life.This study aims at examining whether health-conscious families can reduce and prevent stunting. The study is conducted in the operational area of PT Mifa Bersaudara. The research method used in this study was a quantitative study. This study had been conducted from March to September 2019. The instrument used is the Family Health Indicators issued by the Ministry of Health of Indonesia. The data were analyzed using the formula of health-conscious family index and Z-score. The population is all families in the area of 1,133 households with 293 families having toddlers as the respondents. The results show that the families in the operational area of PT Mifa Bersaudara are mostly in pre-healthy families (51.5%) and there were 88 stunted children. The statistical test results show that there is a relationship between the index of healthy families and the incidence of stunting (p-value<0.05).The logistic regression test shows a significant relationship between the incidence of stunting and the families following the family planning program, exclusive breastfeeding, toddlers receiving monitoring, and no family members smoking. Stunting is associated with health-conscious family. The incidence of stunting in infants and toddlers is associated with families that plan the pregnancy spacing (family planning), babies getting exclusive breastfeeding, toddlers getting growth monitoring, and no smoking family members.
