The full source panel contained 4,095 country-year observations from 195 countries, and the primary complete-case sample included 3,365 observations from 172 countries. Life expectancy at birth was the outcome. Adult obesity prevalence and insufficient physical activity were the main exposures. Models included two-way fixed-effects specifications with country-clustered standard errors, oneyear lagged exposures, a joint lagged specification, country-specific time trends, a non-linear obesity model, a smoking sensitivity analysis, and three-year and five-year lag sensitivity models.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n In standalone lagged models, obesity (\u03b2 = -0.3017, p < 0.001) and insufficient physical activity (\u03b2 = -0.0716, p = 0.020) were inversely associated with life expectancy. In the joint lagged model, obesity remained significant (\u03b2 = -0.2873, p < 0.001), whereas insufficient physical activity attenuated to non-significance (\u03b2 = -0.0153, p = 0.643). In the country-specific time-trends model, obesity remained significant (\u03b2 = -0.2496, p = 0.040), but insufficient physical activity did not (\u03b2 = 0.1325, p = 0.457). Three-year and five-year lag models supported this pattern.<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n In this country-level panel, adult obesity prevalence showed a more robust inverse association with life expectancy than insufficient physical activity. The findings should not be interpreted as evidence that obesity alone causes lower life expectancy. Rather, obesity may represent a cumulative marker of overlapping metabolic, social, environmental, and policy-related processes that shape population longevity.<\/jats:p>\n <\/jats:sec>\n \n Supplementary information<\/jats:title>\n The online version contains supplementary material available at 10.32394\/rpzh\/225361<\/jats:p>\n <\/jats:sec>","DOI":"10.32394\/rpzh\/225361","type":"journal-article","created":{"date-parts":[[2026,7,17]],"date-time":"2026-07-17T10:34:26Z","timestamp":1784284466000},"page":"75-82","source":"Crossref","is-referenced-by-count":0,"title":["Obesity, insufficient physical activity and life expectancy across 172 countries: a longitudinal ecological panel study"],"prefix":"10.32394","volume":"77","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-4798-5968","authenticated-orcid":false,"given":"Ekaterina","family":"Lyulina","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-2598-5918","authenticated-orcid":false,"given":"Gulsara","family":"Asatova","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8648-316X","authenticated-orcid":false,"given":"Lesya","family":"Korobeynikova","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1097-4787","authenticated-orcid":false,"given":"Georgiy","family":"Korobeynikov","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"17323","published-online":{"date-parts":[[2026,7,15]]},"container-title":["Roczniki Pa\u0144stwowego Zak\u0142adu Higieny"],"original-title":[],"link":[{"URL":"https:\/\/roczniki.pzh.gov.pl\/pdf-225361-142489","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/roczniki.pzh.gov.pl\/pdf-225361-142489","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,7,17]],"date-time":"2026-07-17T12:26:26Z","timestamp":1784291186000},"score":1,"resource":{"primary":{"URL":"https:\/\/roczniki.pzh.gov.pl\/Obesity-insufficient-physical-activity-and-life-expectancy-across-172-countries-a,225361,0,2.html"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,7,15]]},"references-count":0,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2026]]}},"alternative-id":["225361"],"URL":"https:\/\/doi.org\/10.32394\/rpzh\/225361","relation":{},"ISSN":["0035-7715","2451-2311"],"issn-type":[{"value":"0035-7715","type":"print"},{"value":"2451-2311","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,7,15]]}}}
