“…8 A study conducted in Japan found that EBF for at least six months was associated with a lower risk of AD (OR 0.70; 95% CI 0.52-0.93). 9 While the protective effect of breastfeeding against AD has been reported in many studies, there is limited research on this topic in Saudi Arabia, particularly in the Al Madinah region (AL-Hijaz area of Western Saudi Arabia). This is the desert region where the summers are harsh, and there is no humidity in the area.…”

Background: Atopic dermatitis (AD) is a common skin condition in infants, and breastfeeding has been proposed as a potential protective factor. The study aims to investigate the prevalence of AD in infants based on guardians' reports and the impact of exclusive breastfeeding (EBF) and formula feeding on the incidence of AD among Saudi infants in the Al Madinah region. Methods: A cross-sectional survey of 200 mothers with infants was conducted using a structured questionnaire. Data collected included demographics, breastfeeding practices, infant characteristics, allergies, and AD diagnosis. Statistical analysis employed chi-square. Results: There were a total of 200 infants, out of which 145 (72.5%) had AD, as confirmed by pediatricians. Gender was significantly associated with the prevalence of AD. Based on their nutritional source, 62 (42.8%) were on EBF, and 83 (57.2%) were non-EBF. Infant nutrition was found to be significantly associated with the hospitalization time of infants because of AD. Other AD risk factors, such as parental allergies, feeding frequencies, and frequency of AD episodes, were not significantly associated with the type of feeding. Conclusions: This study found that AD is quite prevalent in the Al Madinah region of Saudi Arabia. AD was more prevalent in male infants than in females. It suggests that EBF may be a protective factor against hospitalization of Saudi infants because of AD.

BackgroundThe role of the climate regarding atopic dermatitis (AD) in infants is still unclear. This study aimed to determine the relationship between meteorological conditions and the incidence of early AD.MethodsThe study was conducted using a retrospective design. We analyzed children aged 0–24 months with clinically diagnosed AD (n = 603), including infantile eczema (IE, n = 292), in relation to the mean monthly meteorological data in Minsk. The Mantel–Haenszel method was used to study the association between an AD outcome and meteorological variables, stratifying by potential confounders. Seasons of birth were analyzed in children diagnosed with AD before 6 months of age (n = 567) and at 12 months of age (n = 350) from 2005 to 2019.ResultsThe incidence rate of IE was negatively associated with air temperature (adjusted incidence rate ratio = 0.75; 95% confidence interval (CI) 0.59–0.94), precipitation (0.74; 95% CI 0.58–0.93), and positively associated with atmospheric pressure (1.31; 95% CI 1.04–1.66). The highest incidence rate of IE was during spring, and the lowest was during summer. Incidences of AD were less frequent among infants born in the spring (18.1% vs. 29.4%, P < 0.001) than among older children. The principal component analysis identified three meteorological combinations where the first one (warm, low humidity) was negatively associated with the incidence rate of AD among children aged 0–24 months (0.77; 95% CI 0.65–0.92), and the third one (rainy, low atmospheric pressure) with IE (0.70; 95% CI 0.54–0.90).ConclusionContinental seasonal cold‐humid weather may influence early AD incidence. Moreover, short‐term meteorological factors may play an important role in the onset of IE.
