“…However, the prevalence of doctor‐diagnosed asthma reported in this study is within the range of those reported in the global pediatric asthma prevalence surveys on African children with reported proportions from 2.5% in Ethiopia and Burkina Faso to almost 10% in Swaziland . The prevalence of doctor‐diagnosed asthma from recent cross‐sectional studies from other low‐ and middle‐income countries were as high as 7.5% in Iran, 6% in India, 4.8% in China, 3% in Senegal, 2.5% in Mongolia, to 2% in Georgia …”

Asthma‐related outcomes associated with indoor air pollutants among schoolchildren from four informal settlements in two municipalities in the Western Cape Province of South Africa

The health impact of indoor air pollution in informal settlement households has not been extensively studied in South Africa. This cross‐sectional study investigated the association between asthma and common indoor exposures among schoolchildren from four informal settlements located in two municipalities in the Western Cape Province. A total of 590 children, aged 9‐11 years, were recruited. The International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire was administered to caregivers. Pulmonary function assessment included spirometry and fractional exhaled nitric oxide (FeNO). Phadiatop test for atopy was done. The prevalence of doctor‐diagnosed asthma was 3.4% (n = 20) among whom only 50% were on treatment. The prevalence of current wheeze was 12.9%, and 17.6% had airway obstruction (FEV1 < lower limit of normal), while 10.2% had airway inflammation (FeNO > 35 ppb). In adjusted logistic regression models, dampness, visible mold growth, paraffin use for cooking, and passive smoking were associated with a twofold to threefold increased risk in upper and lower airway outcomes. The strongest association was that of visible mold growth with rhinitis (adjusted odds ratio—aOR 3.37, 95% CI: 1.69‐6.71). Thus, there is a need for improved diagnosis of childhood asthma and Indoor Air Quality in informal settlement households.

“…25 A recent study in children and adolescents reported that the prevalence of asthma in adolescents (aged 13-14 years) was significantly higher than that in schoolchildren aged 6-7 years. 26 This study also found that the severity of asthma in girls was higher than that in boys aged 13-14 years. In older adults, two phenotypes are usually observed: patients with longstanding asthma who develop additional airflow limitation, and those who develop late-onset asthma.…”

Sex-based disparities have been identified in respiratory physiology, and in many chronic lung diseases including asthma, chronic obstructive pulmonary disease, and cystic fibrosis. The observed sex differences in lung disease prevalence and incidence have been linked to changes in circulating levels of sex hormones that start after puberty and that have been shown to affect physiological and immunological functions. While the exact roles of male and female sex hormones in these processes have not been fully elucidated, it is now evident that these can target many lung cell types and affect several functions of the respiratory system. In this mini-review, we have summarized seminal studies aimed to understand the effects of the most relevant male and female sex hormones (estrogens, progesterone, and androgens) and their receptors on lung function. Moreover, we have reviewed the known influences of sex hormones and of the hypothalamic–pituitary–gonadal axis in lung disease and immunity. Understanding the roles of sex hormones in the regulation of lung function and inflammation is the first step for the potential development of more effective therapeutic options to prevent and treat lung disease in men and women. Impact statement Sex-differences in the incidence and severity of inflammatory lung diseases have been recognized for years. Women of reproductive age are more likely to suffer from chronic lung disease, with higher mortality rates than men. Physiological changes in hormone levels such as those occurring during the menstrual cycle, pregnancy, and menopause have been associated with lung function changes and asthma symptoms. Despite this, the roles of sex hormones in the mechanisms associated with lung diseases have not been fully elucidated. This review summarizes basic and clinical studies of sex hormones as potential modulators of lung function and inflammation. The information obtained from sex-specific research on lung physiology and pathology will potentially help in the development of sex-specific therapeutics for inflammatory lung disease that may account for the hormonal status of the patient.

BACKGROUND: Bronchial asthma among children is a common chronic disease which may have impact on quality of life. Health education is one of the strategy to improve knowledge and quality of life.OBJECTIVE: The study aims to assess the effect of health education via mobile application (app) in promoting quality of life among schoolchildren with asthma in urban Malaysia.METHODS: A quasi-experimental, pre- and post-intervention design was used in this study during the period September 2016 until April 2017 involving a total of 214 students, randomly assigned into two groups (intervention group and control group). The control group received face-to-face health education while the experimental group received health education via a mobile application.RESULTS: The findings showed that the total score of quality of life (QoL) has improved from a mean total score at pre-intervention (5.31±1.27) to post-intervention (5.66±1.28) for the control group, compared with the experimental group with a mean total score of QoL at pre-intervention (5.01±1.36) and post-intervention (5.85±1.29). A comparison between the experimental and control groups using an independent t-test showed statistically significant differences in their mean QoL scores. The effect of health education via mobile application showed a statistically significant improvement in the mean QoL score from pre- to post-intervention [F (1,288) = 57.46, p = <0.01].CONCLUSION: The use of mobile technology in health education improved QoL as compared to the traditional methods of face-to-face lecture and/or handbooks among schoolchildren with asthma. Thus, educational modules using mobile applications do improve QoL.
