Aktivitas fisik merupakan salah satu faktor penting dalam pencegahan penyakit tidak menular. Meskipun demikian, data mengenai aktivitas fisik dan faktor-faktor yang berhubungan dengannya pada tingkat kecamatan masih terbatas, termasuk di Kecamatan Tarumajaya. Penelitian ini bertujuan menganalisis faktor-faktor yang berhubungan dengan aktivitas fisik pada masyarakat Kecamatan Tarumajaya, Kabupaten Bekasi tahun 2026.

Mayoritas responden berusia dewasa awal, berjenis kelamin laki-laki, memiliki pekerjaan dengan aktivitas fisik pasif, pengetahuan yang baik mengenai aktivitas fisik, mendapatkan dukungan tetangga, serta menilai fasilitas aktivitas fisik di lingkungannya mendukung. Hasil analisis bivariat menunjukkan bahwa dukungan keluarga berhubungan signifikan dengan aktivitas fisik (p=0,023; OR=3,01; 95% CI=1,13–8,03). Sementara itu, usia, jenis kelamin, pekerjaan, pengetahuan, dukungan tetangga, dan fasilitas aktivitas fisik tidak menunjukkan hubungan yang signifikan dengan aktivitas fisik. Mayoritas masyarakat Kecamatan Tarumajaya telah memenuhi rekomendasi aktivitas fisik yang dianjurkan. Dukungan keluarga merupakan faktor yang berhubungan dengan aktivitas fisik, sedangkan faktor individu, dukungan tetangga, dan fasilitas aktivitas fisik tidak menunjukkan hubungan yang signifikan.

Physical activity is an important factor in preventing non-communicable diseases. However, evidence regarding physical activity and its associated factors at the sub-district level remains limited, including in Tarumajaya District. This study aimed to analyze factors associated with physical activity among the community of Tarumajaya District, Bekasi Regency, in 2026. A cross-sectional study was conducted among 205 residents of Tarumajaya District. Data were collected through an online questionnaire. Physical activity was measured using the International Physical Activity Questionnaire (IPAQ) and categorized based on MET-minutes/week. Data were analyzed using univariate and bivariate analyses with the Chi-square test. Most respondents had sufficient physical activity levels (89.27%). The majority were young adults, male, had physically passive occupations, possessed good knowledge of physical activity, received neighborhood support, and perceived local physical activity facilities as supportive. Bivariate analysis showed that family support was significantly associated with physical activity (p=0.023; OR=3.01; 95% CI=1.13–8.03). In contrast, age, sex, occupation, knowledge, neighborhood support, and physical activity facilities were not significantly associated with physical activity. Most residents of Tarumajaya District met the recommended level of physical activity. Family support was significantly associated with physical activity, while individual factors, neighborhood support, and physical activity facilities showed no significant association.
