Examining the decline in modern contraception usage among married women in Bangladesh: Applying Blinder-Oaxaca decomposition analysis.

OBJECTIVES: Controlling population expansion and reducing unintended pregnancies through the use of modern contraceptives is a cost-effective strategy. In recent years, the rate of modern contraceptive use in Bangladesh has been declining. So, this study aimed to investigate the associated factors of the deterioration in modern contraceptive usage. METHODS: This study used data from two successive Bangladesh Demographic and Health Surveys (2014 and 2017-18) and applied the Blinder-Oaxaca decomposition analysis to understand the drivers. A popular binary logistic regression model is fitted to determine the factors that influence the use of modern contraceptive methods over the years. RESULTS: This study revealed that highly educated women were more likely to use modern contraception methods, and their use increased by 3 percent over the years. Factors such as women's working status, husband's education, number of living children, and fertility preference were found significantly associated with decreased usage of modern contraception methods over years. The result of the Blinder-Oaxaca (BO) decomposition analysis found a significant decrease between 2014 and 2018. Respondent's age, working status, husband's age, opinion on decision making, region, and media exposure were the most significant contributors to explaining the shift between 2014 and 2018. The two factors that contributed most to narrowing the difference between the two surveys were women's decision on own health (26%), and employment status (35%). CONCLUSIONS: The factors that influence modern contraceptive prevalence are important to know for policy implication purposes in Bangladesh. The findings indicate the need for further improvement of factors for balancing the usage of modern contraception methods.

Study of nasal mucosa histopathological changes in patients with hypersensitivity pneumonitis.

Hypersensitivity pneumonitis (HP) is an interstitial lung disease that develops after inhalation of a variety antigens in susceptible individuals. The nasal mucosa is constantly exposed to these antigens that can irritate the respiratory mucosa. So, the purpose of this study was to study nasal histopathological changes in order to identify any shared pathological changes between the upper airways and the well-known pathological features of HP. 40 HP patients diagnosed at the Chest Department, Kasr Alainy hospital following ATS/JRS/ALAT guidelines were included. Patients were subjected to thorough history, high-resolution computed tomography, spirometry, cough evaluation test (CET), sinonasal outcome test-22 (SNOT-22), sinonasal examination and nasal mucosal biopsy by an otolaryngologist under visualization by a rigid nasal endoscope. The mean age of the patients was 46.2 ± 13.5 (85% were females and 15% were males). 90% of patients presented with cough and the mean CET was 17.15 ± 5.59.77.5% of patients suffered from sinonasal symptoms and the mean SNOT-22 was 12.18 ± 3.8. There was a significant correlation between the burden of sinonasal symptoms represented by the SNOT-22 and the severity of the cough represented by CET (r 0.40, p 0.01). 87.5% of HP patients had chronic inflammation of the nasal mucosa with predominant lymphocytic infiltration in 72.5% of patients. 77.5% of HP patients had a high burden of sinonasal symptoms which is positively associated with cough severity. 72.5% of patients had predominately lymphocytic infiltration of the nasal mucosa.Trial registration: retrospectively registered, registration number is NCT05723796, date of registration 13/02/2023.

Comparison of weighted and unweighted methods of wealth indices for assessing SOCIO-ECONOMIC status.

Due to some of the limitations of monetary measures, various non-monetary approaches for assessing household wealth have been developed as alternative tools for classifying household socio-economic status. Among them, wealth indices based on household durable assets are being used. The literature revealed that two basic methods of constructing wealth indices are employed: an unweighted method, where assets are weighted equally; and a weighted method, where specific weights are assigned to assets. In the case of using the weighted method, weighting can be assigned using various techniques. The overall objective of the study is to compare the wealth indices constructed by using weighted and unweighted methods for assessing the socio-economic status of households in rural Bangladesh. Firstly, the study attempts to construct wealth indices based on durable assets using the unweighted method and two techniques of the weighted method: weighted index using the inverse of proportion, and weighted index using principal component analysis (PCA). Following this, the study compares some distributional characteristics of these indices as well as monetary indicators. At the same time, the study evaluates and examines some attractive properties of these indices such as the extent of clumping and truncation, consistency with traditional monetary measures. Comparative analysis revealed that the unweighted asset index, as well as weighted asset index using PCA, can be treated as an efficient alternative to the monetary measures to evaluate the living standard of the households in the present study. However, due to some advantage's asset index using PCA can be considered to be somewhat better than the unweighted index. But, as the unweighted asset index is not very different from the weighted asset index using PCA, it can also be used as an alternative to the monetary measures without the need to use weighting.
