Household food security refers to the condition in which all household members have sufficient, safe, nutritious, and sustainable access to food, enabling them to live healthy and active lives. Food security is one of the key factors influencing the quality of household food consumption. This study aims to examine the relationship between household food security with energy and protein intake among housewives living in the coastal area of Leato Selatan Urban Village, Gorontalo City. This quantitative study with a cross-sectional approach used 166 housewives selected through purposive sampling from a population of 281 participants. Household food security was assessed using the Household Food Insecurity Access Scale (HFIAS) questionnaire, while energy and protein intake were measured using a 3 x 24-hour non-consecutive food recall method. Data were analyzed using the Spearman correlation test with a significance level of p < 0.05. The findings revealed that the majority of households were categorized as mildly food insecure (56.6%), followed by food secure (199%), moderately food insecure (13.3%), and severely food insecure (10.2%). Furthermore, most housewives had normal energy and protein intake levels. In addition, the Spearman correlation analysis demonstrated significant relationships between household food security and energy intake (p = 0.010) and protein intake (p=0.000). In conclusion, most households in the coastal area of Leato Selatan Urban Village experienced mild food insecurity, and household food security was significantly associated with both energy and protein intake among housewives. Therefore, relevant stakeholders are encouraged to strengthen nutrition education and food security programs for coastal communities.
