Paediatric asthma exacerbation admissions and stringency of non-pharmaceutical interventions: Results from a developing country.

BACKGROUND: Non-pharmaceutical interventions (NPI) mitigation measures implemented to mitigate COVID-19 has brought unprecedented global impact. Changes in daily living routines, reduction in physical activities, and changes in environmental indicators were suggested to positively impact paediatric asthma indicators in western cultures. Little is known about such impact in developing countries. This study investigated the potential impact of COVID-19 NPI measures on paediatric asthma exacerbation admissions in Northern Jordan. METHODS: Aggregate data from a paediatric hospital, Princess Rahma Pediatric Teaching Hospital, and King Abdulla University Teaching Hospital were utilised from 2018 to 2020. The number of paediatric asthma exacerbation admissions was calculated by week and compared by year, lockdown status, and weeks for lockdown (weeks 13-19). The stringency index was correlated with the number of weekly paediatric asthma exacerbation admissions for 2020. RESULTS: A total of 1,207 paediatric asthma exacerbation admissions were reported; 40.3%, 35.2%, and 24.5% in 2018, 2019 and 2020, respectively. The number of weekly admissions ranged from 1 to 13 paediatric asthma cases (mean (SD) = 7.6 (2.7)). In 2018 and 2019, respectively, mean weekly admissions were 9.2 (1.9) and 8.0 (2.0) paediatric asthma cases, while in 2020 the mean was 5.6 (2.7) cases. Significant differences in mean weekly paediatric asthma exacerbation admissions were detected by year, with mean weekly admissions for 2020 being significantly lower than that for 2018 and 2019. During the lockdown (22 March to 1 May 2020), mean weekly admissions (2.6 (1.4)) was significantly lower than that before the lockdown (8.6 (2.0)) and after the lockdown (5.2 (2.0)). For the lockdown weeks only, the mean admissions for the year 2020 was significantly lower than that for years 2019 and 2018. The stringency index negatively correlated with the number of weekly admissions. CONCLUSION: NPI measures in Jordan seem to have positively impacted paediatric asthma exacerbation admissions. Further studies are needed to draw public health policies and fine-tune environmental and community policies.

Hb level in relation to vitamin D status in healthy infants and toddlers.

OBJECTIVE: To assess the presence of an association between vitamin D deficiency and anaemia in Jordanian infants and toddlers, in whom both vitamin D deficiency and anaemia have previously been proved to be common separately. DESIGN: Cross-sectional prospective study. SETTING: Department of Paediatrics, Princess Rahma Teaching Hospital, Jordan. SUBJECTS: Healthy infants and children aged 6-36 months who were seen for primary care. RESULTS: Out of 203 infants and toddlers included in the study, the anaemia prevalence was 40·4 %. The prevalence of anaemia among infants (n 110) was 51·8 %, whereas it was 26·9 % among toddlers (n 93). No association between vitamin D status and anaemia was found. CONCLUSIONS: Vitamin D deficiency is not a risk for anaemia in infants and toddlers.

Vitamin D deficiency among healthy infants and toddlers: a prospective study from Irbid, Jordan.

BACKGROUND: The aim of this study was to estimate the prevalence of vitamin D deficiency among healthy infants and toddlers, as well as its associated factors, in Irbid, Jordan. METHODS: A total of 275 subjects (136 infants and 139 toddlers) aged 6-36 months participated in this study. Information concerning sociodemographic characteristics and early feeding patterns was collected using a self-guided questionnaire. Plasma vitamin D, calcium, phosphorous, and alkaline phosphatase activity were measured. RESULTS: The prevalence of vitamin D deficiency was 28% (16.7% for severe vitamin D deficiency and 11.3% for vitamin D deficiency) and vitamin D insufficiency was 28.4%. Plasma calcium and alkaline phosphatase levels showed no correlation with the vitamin D status of the study population. For both age groups, a significant association was found between vitamin D status and sun exposure (P < 0.001). A significant association between infant feeding practices and vitamin D status was found (P < 0.001). Infants who were exclusively breast-fed had higher risk for vitamin D deficiency and vitamin D insufficiency than those who were bottle-fed. Multivariate logistic regression analyses results showed that female sex, low sun exposure and exclusive breast-feeding were the main determinants of vitamin D levels. CONCLUSION: The prevalence of vitamin D deficiency is considered to be high among northern Jordanian infants and toddlers. Sun exposure of less than 30 min daily and exclusively breast-feeding are the main factors for developing vitamin D deficiency.
