Validation of the Arabic version of the breastfeeding behavior questionnaire among Lebanese women.

Int Breastfeed J 2020 06 9;15(1):54. Epub 2020 Jun 9.

Department of Pediatrics and Adolescent Medicine, American University of Beirut, Beirut, Lebanon.

Background: The Breastfeeding Behavior Questionnaire (BBQ) assesses women's perceptions of their breastfeeding behavior. It was adapted to several languages and used in different settings, but has not been validated in Arabic-speaking populations. None of the previous studies that used the BBQ in other cultures examined its ability to predict the actual breastfeeding behaviors of mothers postpartum. This study validated the BBQ in a cohort of Lebanese pregnant women between December 2013 and January 2016, and examined whether it can predict exclusive breastfeeding at one, three and six months.

Methods: The internal consistency reliability and construct validity of the Arabic BBQ (BBQ-A) were tested on 354 pregnant women. Its predictive ability was assessed by correlating the women's BBQ-A scores with their breastfeeding outcomes at one, three and six months post-delivery.

Results: The BBQ-A had a good internal consistency reliability (Cronbach's alpha = 0.78). Exploratory factor analysis revealed that it is unidimensional. Inter-item correlations ranged between - 0.016 and 0.934, with corrected-item total correlations ranging from 0.273 to 0.678. Perceived positive breastfeeding behavior correlated with positive breastfeeding attitudes, good breastfeeding knowledge and stronger breastfeeding intention supporting its external validity. However, in binomial multivariate logistic regression analysis, the BBQ-A did not predict exclusive breastfeeding at one, three or six months.

Conclusions: The BBQ-A is a reliable and valid instrument to assess women's perceptions of their breastfeeding behavior in an Arab context. Availability of this instrument is important for investigators conducting breastfeeding research in the Arab world. However, the BBQ-A does not predict exclusive breastfeeding at one, three or six months. Further research on the Breastfeeding Behavior Questionnaire is needed to examine its predictive validity in other cultures.

Knowledge and attitudes towards E-cigarette use in Lebanon and their associated factors.

BMC Public Health 2020 Feb 28;20(1):278. Epub 2020 Feb 28.

Epidemiology and Population Health Department, Faculty of Health Sciences, American University of Beirut, P.O.Box 11-0236 Riad El-Solh, Beirut, 1107 2020, Lebanon.

Background: Despite the misconceptions regarding E-cigarettes (ECs), only a few studies have been conducted in the Middle East that focused on this topic. This study assesses the knowledge of and attitudes towards ECs in Lebanon, determines how these two measures are associated, and identifies the variables that explain each of these measures.

Methods: A cross sectional study was conducted on a convenience sample of Lebanese pedestrians aged between 18 and 64 inclusive. A structured self-administered questionnaire comprising of knowledge and attitude scales, and questions on demographical, health and smoking characteristics was used.

Results: Scores for attitudes and knowledge of ECs were summed and dichotomized using a 75% cutoff, above which the participant was considered to have a positive attitude and good knowledge. Among the 352 participants (56.6% males, 43.3% females, mean age 30.3, 46.2% smokers), 63.3% exhibited a lower level of EC knowledge. More than 50% erroneously thought that ECs are not associated with lung and bladder cancer or impair lung and heart function. 65% falsely thought that it is harmless and not addictive. As for attitude, 43.3, 53.9, and 44.3% thought that it is socially acceptable, helps in smoking cessation, and is a good replacement for cigarettes and an enjoyable recreational device respectively. Our results revealed an inverse correlation between attitude and knowledge scores (Spearman's correlation = -.30, p < .001). Predictors of knowledge included health-related occupation (p = .010), regular exercise (p = .016), healthy diet (p = .026), EC use (p = .026), perception that ECs are not harmful (p = .001), and help in smoking cessation (p = .017). Predictors of attitude included EC use (p = .008), sex (p = .010), and knowledge that most ECs are addictive (p = .006), harmful (p = .014), and impair heart and lung function (p = .047).

Conclusions: Our study revealed a gap in EC knowledge, especially among participants who displayed a positive attitude towards ECs. Hence, measures should be undertaken to regulate its use by instituting more stringent laws and holding nationwide awareness campaigns.

Musculoskeletal disorders in hemodialysis patients: different disease clustering according to age and dialysis vintage.

Clin Rheumatol 2020 Feb 7;39(2):533-539. Epub 2019 Nov 7.

Rheumatology Department, Hotel-Dieu de France Hospital, Saint-Joseph University, Beirut, Lebanon.

Musculoskeletal disorders remain a major problem in hemodialysis patients. The aim of the study was to estimate the prevalence of musculoskeletal manifestations in hemodialysis patients and identify disease cluster profiles. We performed a cross-sectional study including all adult patients in the hemodialysis unit at Hotel-Dieu de France Hospital. We collected demographic characteristics, musculoskeletal symptoms, biologic parameters, and treatments. Musculoskeletal disorders were classified by a rheumatologist into predefined diagnostic categories. Prevalence was presented, and a cluster analysis was performed. Eighty-nine patients were included, mean age was 67.5 ± 12 years, and 43.8% were female. Dialysis vintage was 5.7 ± 5.37 years. Musculoskeletal symptoms were reported by 76.4% of the patients. Pain was the most frequent symptom (44.9%). The main diagnoses were osteoarthritis (53.9%) and fracture (27%). Musculoskeletal symptoms and disorders were significantly associated with dialysis vintage and age. Cluster analysis identified three patient profiles: younger with low calcium levels, younger but long dialysis vintage with osteoarthritis and carpal tunnel syndrome, and older with long dialysis vintage and fractures. The prevalence of musculoskeletal manifestations is high in the hemodialysis population and increases with dialysis vintage. Musculoskeletal disorders cluster according to age and dialysis vintage. Key Points• Musculoskeletal symptoms are highly prevalent among hemodialysis patients (76.4%).• All musculoskeletal disorders are associated with dialysis vintage and age.• Three clusters are identified among hemodialysis patients: young with low calcium levels, young but long dialysis vintage with osteoarthritis and carpal tunnel syndrome and old with long dialysis vintage with fractures.
