Maternal and child health (MCH) service utilization may represent an important pathway linking adolescent motherhood with child survival, but evidence from Pakistan remains limited. This study examined the association between adolescent motherhood and under\u2010five mortality and assessed the statistical indirect association through MCH service utilization.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We analyzed nationally representative data from the 2018 Pakistan Demographic and Health Survey, including 8159 mother\u2013child observations. Under\u2010five mortality was examined as a time\u2010to\u2010event outcome. We used multivariable generalized structural equation modeling with a Weibull proportional hazards specification to estimate associations between adolescent motherhood, MCH service utilization, and under\u2010five mortality. We constructed the MCH service utilization index from indicators of antenatal care, skilled delivery care, and postnatal care. Indirect associations were evaluated using 5000 bootstrap replications and 95% bias\u2010corrected bootstrap confidence intervals. All analyses were conducted using STATA version 17.1.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Overall, 4.09% of children died before age five, and 37.55% were born to adolescent mothers. After adjustment for prespecified covariates, adolescent motherhood was associated with higher under\u2010five mortality (HR\u2009=\u20092.05,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001) and lower MCH service utilization (\n                      <jats:italic>\u03b2<\/jats:italic>\n                      \u2009=\u2009\u22120.02,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.044).

After accounting for MCH service utilization, adolescent motherhood remained associated with higher under\u2010five mortality (HR\u2009=\u20091.99,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001).

The findings suggest that differences in MCH service utilization account for part of the observed association between adolescent motherhood and under\u2010five mortality. Improving access to and utilization of MCH services, alongside interventions addressing adolescent pregnancy and broader social determinants of child health, may contribute to improved child survival in Pakistan.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/ajhb.70332","type":"journal-article","created":{"date-parts":[[2026,9,8]],"date-time":"2026-09-08T05:54:35Z","timestamp":1788846875000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Direct and Indirect Effects of Adolescent Motherhood on Under\u2010Five Mortality in Pakistan: Evidence From a Nationally Representative Survey"],"prefix":"10.1002","volume":"38","author":[{"given":"Naeem","family":"Rabbani","sequence":"first","affiliation":[{"name":"School of Public Policy and Administration Xi'an Jiaotong University  Xi'an China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3850-4752","authenticated-orcid":false,"given":"Zhongliang","family":"Zhou","sequence":"additional","affiliation":[{"name":"School of Public Policy and Administration Xi'an Jiaotong University  Xi'an China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-1818-1749","authenticated-orcid":false,"given":"Rashed","family":"Nawaz","sequence":"additional","affiliation":[{"name":"School of Public Health and Health Nutrition Luohe Medical College  Luohe Henan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-0476-6420","authenticated-orcid":false,"given":"Neelum","family":"Khalid","sequence":"additional","affiliation":[{"name":"School of Public Policy and Administration Xi'an Jiaotong University  Xi'an China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,9,7]]},"reference":[{"key":"e_1_2_13_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1651\u20102227.2007.00117.x"},{"issue":"1","key":"e_1_2_13_3_1","first-page":"3","article-title":"Factors Associated With Teenage Pregnancy in South Asia: A Systematic Review","volume":"4","author":"Acharya D.
