Introduction: Teenage pregnancy is a persistent global health challenge, with an estimated 13% of females below 18 years having given birth in 2022 (UNICEF, 2024). In the Philippines, approximately 5% of females aged 15–19 years have experienced pregnancy or childbirth (PSA, 2022). This study evaluated the nutritional and health status, nutrient intake, health-seeking behaviours, and participation in government programmes among pregnant adolescents (PAs) aged 10-19 years in selected municipalities in Batangas, Laguna, and Quezon Provinces. Methods: A crosssectional design was employed in 2022, involving 165 PAs and 28 key informants (KIs) interviewed via mobile or video calls during the COVID-19 pandemic. Energy and nutrient intake were assessed using a 24-hour food recall. Results: Among participants (mean age 17.7 years), 50% were nutritionally at risk, 70% had normal blood pressure, 24% were pre-hypertensive, and 6% were hypertensive. Mean energy intake ranged from 2,267 kcal (16–18 years) to 2,791 kcal (13–15 years), with only one-third to one-half meeting recommended intake levels (p=0.087). Protein adequacy ranged from 59 to 70%, while calcium (28–39%) and iron (5–10%) intakes were markedly deficient. Niacin adequacy differed significantly across age groups (p=0.036). These findings align with national data, where only 14.9% of PAs meet energy intake, and 23% are anaemic (DOST-FNRI, 2023). Cultural beliefs (67.3%) and food fallacies (53.3%) were common, while 64% said needed programmes and services were available. Conclusion: The findings highlighted significant nutritional deficiencies, underscoring the need for intensified monitoring, targeted nutritional interventions, and comprehensive educational strategies to support adolescent maternal health.
