RESUMO
Background and aims: The study aimed to examine parental, longitudinal and current associative factors for atopic dermatitis (AD) and to compare those to other atopic diseases in 46-year-old adults. Methods: Questionnaire data from the Northern Finland Birth Cohort 1966 study were used. To analyze allergic sensitization, skin prick tests (n = 5373) were performed for birch, timothy, cat, and house dust mite at age 46. Results: Maternal (odds ratio [OR] 1.81; 95% confidence interval [CI] 1.25-2.59) and paternal allergy (OR 2.54; CI 1.76-3.64), sensitization to any of the four tested aeroallergens (OR 1.56; CI 1.04-2.30) as well as polysensitization (OR 3.04; CI 2.10-4.37) were associated with current AD. Living on a farm in infancy was negatively associated with allergic rhinitis, allergic conjunctivitis, and atopic multimorbidity. Current AD (OR 2.65; CI 1.44-4.60) and all atopic diseases associated with indoor air related symptoms. Current AD associated with other atopic diseases, most strongly with allergic rhinitis (OR 4.92; CI 3.92-6.22). Conclusion: Current AD in a 46-year-old general population occurred frequently with allergic rhinitis, allergic conjunctivitis, and asthma in the Northern Finland Birth Cohort study 1966. Parental allergy and sensitization to common aeroallergens were found as shared associative factors for AD, allergic rhinitis, allergic conjunctivitis, and asthma. AD and other atopic diseases associated with symptoms related to poor indoor air quality. In daily practice, it is important to take these comorbidities into consideration when treating patients with AD.
RESUMO
BACKGROUND/OBJECTIVES: To determine the prevalence of skin findings and skin diseases in adults aged 70 and older, and to study the association between cutaneous diseases and socioeconomic status (SES), sex, and living status in the older population. DESIGN: Cross-sectional study of Finnish adults aged 70 to 93 as part of the Northern Finland Birth Cohort 1966 Study. SETTINGS: Skin examination data were available for 552 adults. MEASUREMENTS: A whole-body skin examination was performed by dermatologists. The associations between skin diseases and SES, sex, and living status were analyzed. RESULTS: Nearly 80% of the adults had at least one skin disease that required further treatment or follow-up. More than one-third of the study cases (39.1%) had three or more simultaneous skin diseases. Skin diseases were more common in men than in women (P < .001). The most common skin diseases were tinea pedis (48.6%), onychomycosis (29.9%), rosacea (25.6%), actinic keratosis (22.3%), and asteatotic eczema (20.8%). Some association was found between skin diseases and SES and living status. CONCLUSION: A whole-body clinical skin examination is important because it reveals important diagnoses.
