The data were analyzed between February 23, 2022, and March 20, 2024.<\/jats:p>\n <\/jats:sec>\n \n Exposure<\/jats:title>\n The primary exposure was 24-hour urinary sodium excretion.<\/jats:p>\n <\/jats:sec>\n \n Main Outcome and Measure<\/jats:title>\n The primary outcome was AD or active AD based on diagnostic and prescription codes from linked electronic medical records. Multivariable logistic regression models adjusted for age, sex, race and ethnicity, Townsend Deprivation Index, and education were used to measure the association.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n The analytic sample comprised 215\u202f832 participants (mean [SD] age, 56.52 [8.06] years; 54.3% female). Mean (SD) estimated 24-hour urine sodium excretion was 3.01 (0.82) g per day, and 10\u202f839 participants (5.0%) had a diagnosis of AD. Multivariable logistic regression revealed that a 1-g increase in estimated 24-hour urine sodium excretion was associated with increased odds of AD (adjusted odds ratio [AOR], 1.11; 95% CI, 1.07-1.14), increased odds of active AD (AOR, 1.16; 95% CI, 1.05-1.28), and increased odds of increasing severity of AD (AOR, 1.11; 95% CI, 1.07-1.15). In a validation cohort of 13\u202f014 participants from the National Health and Nutrition Examination Survey, a 1 g per day higher dietary sodium intake estimated using dietary recall questionnaires was associated with a higher risk of current AD (AOR, 1.22; 95% CI, 1.01-1.47).<\/jats:p>\n <\/jats:sec>\n \n Conclusions and Relevance<\/jats:title>\n These findings suggest that restriction of dietary sodium intake may be a cost-effective and low-risk intervention for AD.<\/jats:p>\n <\/jats:sec>","DOI":"10.1001\/jamadermatol.2024.1544","type":"journal-article","created":{"date-parts":[[2024,6,5]],"date-time":"2024-06-05T12:16:48Z","timestamp":1717589808000},"page":"725","source":"Crossref","is-referenced-by-count":26,"title":["Sodium Intake and Atopic Dermatitis"],"prefix":"10.1001","volume":"160","author":[{"given":"Brenda M.","family":"Chiang","sequence":"first","affiliation":[{"name":"Department of Dermatology, University of California, San Francisco"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Morgan","family":"Ye","sequence":"additional","affiliation":[{"name":"Department of Dermatology, University of California, San Francisco"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aheli","family":"Chattopadhyay","sequence":"additional","affiliation":[{"name":"Department of Dermatology, University of California, San Francisco"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yagmur","family":"Halezeroglu","sequence":"additional","affiliation":[{"name":"Department of Dermatology, University of California, San Francisco"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Erin L.","family":"Van Blarigan","sequence":"additional","affiliation":[{"name":"Department of Epidemiology and Biostatistics, University of California, San Francisco"},{"name":"Department of Urology, University of California, San Francisco"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katrina","family":"Abuabara","sequence":"additional","affiliation":[{"name":"Department of Dermatology, University of California, San Francisco"},{"name":"Division of Epidemiology and Biostatistics, University of California, Berkeley"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"10","reference":[{"issue":"2","key":"doi240016r1","doi-asserted-by":"publisher","first-page":"304","DOI":"10.1111\/bjd.v184.2","article-title":"The global burden of atopic dermatitis: lessons from the Global Burden of Disease Study 1990-2017.","volume":"184","author":"Laughter","year":"2021","journal-title":"Br J Dermatol"},{"issue":"10","key":"doi240016r2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0258219","article-title":"The epidemiology of atopic dermatitis in older adults: a population-based study in the United Kingdom.","volume":"16","author":"Chan","year":"2021","journal-title":"PLoS One"},{"issue":"6","key":"doi240016r3","doi-asserted-by":"publisher","first-page":"709","DOI":"10.1093\/bjd\/ljac072","article-title":"Atopic dermatitis across the life course.","volume":"188","author":"Abuabara","year":"2023","journal-title":"Br J Dermatol"},{"issue":"3","key":"doi240016r4","doi-asserted-by":"publisher","first-page":"710","DOI":"10.1016\/j.jaci.2019.05.040","article-title":"Clinical onset of atopic eczema: results from 2 nationally representative British birth cohorts followed through midlife.","volume":"144","author":"Abuabara","year":"2019","journal-title":"J Allergy Clin Immunol"},{"issue":"5","key":"doi240016r5","doi-asserted-by":"publisher","first-page":"1821","DOI":"10.1016\/j.jaci.2018.11.030","article-title":"Atopic eczema and major cardiovascular outcomes: a systematic review and meta-analysis of population-based studies.","volume":"143","author":"Ascott","year":"2019","journal-title":"J Allergy Clin Immunol"},{"issue":"7","key":"doi240016r6","doi-asserted-by":"publisher","first-page":"733","DOI":"10.1093\/ced\/llad080","article-title":"Sodium in the skin: a summary of the physiology and a scoping review of disease associations.","volume":"48","author":"Chattopadhyay","year":"2023","journal-title":"Clin Exp Dermatol"},{"issue":"10247","key":"doi240016r7","doi-asserted-by":"publisher","first-page":"345","DOI":"10.1016\/S0140-6736(20)31286-1","article-title":"Atopic dermatitis.","volume":"396","author":"Langan","year":"2020","journal-title":"Lancet"},{"issue":"1","key":"doi240016r8","doi-asserted-by":"publisher","first-page":"63","DOI":"10.1111\/all.v75.1","article-title":"The exposome in atopic dermatitis.","volume":"75","author":"Stefanovic","year":"2020","journal-title":"Allergy"},{"issue":"6","key":"doi240016r9","doi-asserted-by":"publisher","first-page":"1038","DOI":"10.1111\/bjd.21828","article-title":"Qualitative analysis of the impact of atopic dermatitis on caregivers.","volume":"187","author":"Kim","year":"2022","journal-title":"Br J Dermatol"},{"issue":"4","key":"doi240016r10","doi-asserted-by":"publisher","first-page":"351","DOI":"10.1136\/thoraxjnl-2012-202285","article-title":"Do fast foods cause asthma, rhinoconjunctivitis and eczema?
