Background The objective of the study was to cross-culturally adapt and validate the General Medication Adherence Scale (GMAS) in patients with type-2 diabetes in Morocco. Methods The study was a cross-sectional study conducted between September 12 and October 12, 2022, and included patients with type-2 diabetes from a primary health care network. To measure the different psychometric parameters of the construct, data analysis was performed using SPSS v20. The study was approved by the Moroccan Association for Research and Ethics. Results A total of 284 patients were included in the study; the results of the different psychometric parameters were largely acceptable. Indeed, the improvement of the goodness-of-fit of the model in relation to the independence model was evaluated by the comparative fit index (CFI), which was higher than 0.95, as well as the normalized fit index (NFI), which expresses the percentage of the general covariance between the variable demonstrated via the tested model when the null model is taken as reference and was also higher than 0.95 in this study. Additionally, the Tucker Louis Index (TLI) or Unstandardized Fit Index, which measures the increase in goodness of fit when moving from the reference model to the model under study, had a value of > 0.95. The correlations between the items were good; indeed, the Kaiser-Meyer-Olkin (KMO) index was > 0.7. The translated tool presents good internal consistency; thus, Cronbach’s α had a value of approximately 0.804 (> 0.7). Conclusions The version of the GMAS tool adapted to the Moroccan context has very acceptable psychometric values. This means that Moroccan researchers and health professionals can use it as an instrument to measure adherence among individuals with type-2 diabetes.

Chronic obstructive pulmonary disease (COPD) is a major public health problem that remains largely under-diagnosed, mainly due to the under-use of spirometry to establish the diagnosis. The aim of this study is to evaluate the effectiveness of the Moroccan Arabic dialect version of the COPD Assessment Test (CAT) in screening for COPD. This was a cross-sectional study carried out in primary care facilities in Morocco, involving participants aged 40 and over. The performance of CAT in detecting cases of COPD was measured with reference to the results of spirometry, considered to be the gold Standard. A total of 477 participants were included in the study. The prevalence of COPD was 6.7%. Internal consistency of the Moroccan Arabic dialect version of the CAT was high, with a Cronbach's alpha of 0.89. The total score of the CAT and of each item was significantly higher in subjects with COPD than in those without (P=0.000). Significantly negative correlations were found between CAT total score and FEV1 (r = -0.33, p=0.000), CAT and FVC (r = -0.22, p=0.000), CAT and FEV1/FVC ratio (r = -0.22, p=0.000). The receiver operating characteristic curve showed an area under the curve of 0.93. A CAT score of 10 was the optimal cut-off value for COPD screening, with a sensitivity, specificity, positive predictive value, and negative predictive value of 78.1%, 93.9%, 48.1% and 98.4%, respectively. The results of the present study showed that the CAT could be used as a screening tool for COPD. The use of this tool by healthcare professionals in primary care settings will improve and promote early diagnosis of this chronic disease.

Several epidemiological and toxicological studies have shown that exposure to surface ozone increases deaths and illnesses. Deteriorating air quality could lead to health concerns in emerging countries such as Morocco. The aim of the present study was to investigate the long-term impact of ozone on the health of Agadir residents by using the AirQ+ model. The exposure reference values in 2016 were the daily and yearly average concentrations. Two monitoring stations provided the average ozone concentration per hour. The yearly total of maximum 8-hour ozone levels over 35 ppb was used to forecast probable long-term health impacts. As a health indicator, specific mortality for respiratory disorders was considered. According to the health impact assessment, the yearly cumulative incidence was estimated to 419.5 per 100,000 population. A reduction in ozone concentrations to less than 100 μg/m 3 might prevent 13 deaths per year (95% CI: 5–22), with an estimated attributable proportion of 0.73% (95% CI: 0.26–1.24). AirQ+ can be used as a public health tool to assess the health risks of air pollution, providing policymakers with a basis for implementing air quality management strategies to decrease air pollution's health effect.
