Prevalence of undernutrition among adolescent pregnant women in Dolo-Ado, Somali Region
As shown in Fig. 1, the study assessed the prevalence of undernutrition among pregnant women in Dolo-Ado town using mid-upper arm circumference (MUAC) as an indicator. The mean MUAC of the participants was 24.2 cm (± 2.4 SD), reflecting the average nutritional status of the group and indicating some level of variability among individuals. Among the 380 women interviewed, 79 (21%) were classified as undernourished, defined by a MUAC measurement of less than 22 cm. Meanwhile, 3.2% of the women were found to be severely undernourished, indicating a critical level of nutritional deprivation that demands urgent intervention to prevent adverse maternal and neonatal health outcomes. The remaining 79% of the participants had a normal nutritional status (MUAC ≥ 22 cm), suggesting that the majority of the women met the minimum nutritional requirements to support pregnancy.

Multivariate logistic regression analysis of adolescent pregnant women in Dolo-Ado town
As shown in Table 3, the results indicate that several significant factors are associated with undernutrition among adolescent pregnant women in the Dolo-Ado district.
In the context of maternal education, illiterate mothers were four times more likely to be undernourished compared to their literate counterparts, (AOR) of 3.9 (95% CI: 1.9–8.0). Additionally, pregnant adolescent mothers residing in rural areas were 12 times more likely to experience undernutrition than those living in urban areas (AOR of 12 (95% CI: 3.5–42.9). Regarding monthly family income, households earning less than 1500 Birr had approximately three times the likelihood of undernutrition compared to those with higher incomes, AOR of 2.6 (95% CI: 1.2–5.4).
Food insecurity was identified as a significant predictor of undernutrition. Pregnant adolescents from food-insecure households were six times more likely to be undernourished compared to those from food-secure households, (AOR of 6.2 (95% CI: 2.8–13.9). Furthermore, mothers who consumed five or fewer food groups were 13 times more likely to experience undernutrition, (AOR of 13.1 (95% CI: 2.2–77.3).
Lastly, regarding Iron and Folic Acid (IFA) supplementation, pregnant adolescent mothers who did not receive IFA supplementation were approximately four times more likely to be undernourished compared to those who did receive it, (AOR of 3.6 (95% CI: 1.7–7.5).
