Maternal height, weight in early pregnancy and parity as well as the baby\u2019s sex were identified as physiological variables, with coefficients comparable to findings in other countries. The expected 280-day birthweight, free from pathological influences, of a standard size mother (height 163 cm, weight 64 kg) in her first pregnancy was 3451.3 g. Pathological influences on birthweight within this population included low and high maternal age, low and high body mass index (BMI), smoking, pre-existing and gestational diabetes and pre-existing and gestational hypertension.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec id=\"j_jpm-2018-0219_s_996_w2aab3b7c14b1b6b1aab1c16b4Aa\">\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>The analysis confirmed the main physiological variables that affect birthweight in studies from other countries, and was able to quantify additional pathological factors of maternal age and gestational diabetes. Development of a country-specific customised birthweight standard will aid clinicians in Slovenia with the distinction between normal and abnormal small-for-gestational age (SGA) fetuses, thus avoiding unnecessary interventions and improving identification of at risk pregnancies, and long-term outcomes for infants.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1515\/jpm-2018-0219","type":"journal-article","created":{"date-parts":[[2019,1,17]],"date-time":"2019-01-17T09:01:56Z","timestamp":1547715716000},"page":"270-275","source":"Crossref","is-referenced-by-count":10,"title":["Customised birthweight standard for a Slovenian population"],"prefix":"10.1515","volume":"47","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2597-0188","authenticated-orcid":false,"given":"Tanja","family":"Premru-Srsen","sequence":"first","affiliation":[{"name":"Department of Perinatology, Division of Obstetrics and Gynecology , University Medical Centre Ljubljana , Ljubljana , Slovenia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ivan","family":"Verdenik","sequence":"additional","affiliation":[{"name":"Department of Perinatology, Division of Obstetrics and Gynecology , University Medical Centre Ljubljana , Ljubljana , Slovenia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Barbara","family":"Mihevc Ponikvar","sequence":"additional","affiliation":[{"name":"National Institute of Public Health , Ljubljana , Slovenia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Oliver","family":"Hugh","sequence":"additional","affiliation":[{"name":"Perinatal Institute , Birmingham , UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andre","family":"Francis","sequence":"additional","affiliation":[{"name":"Perinatal Institute , Birmingham , UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jason","family":"Gardosi","sequence":"additional","affiliation":[{"name":"Perinatal Institute , Birmingham , UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"374","published-online":{"date-parts":[[2019,1,17]]},"reference":[{"key":"2023033123573033003_j_jpm-2018-0219_ref_001_w2aab3b7c14b1b6b1ab2b1b1Aa","doi-asserted-by":"crossref","unstructured":"Morais M, Mehta C, Murphy K, Shah PS, Giglia L, Smith PA, et al.
