In response to the diverse health challenges faced by today’s youth and their extensive time spent in schools, we conducted a school health awareness campaign aimed at prioritizing well-being and academic performance. This analytical longitudinal study, spanning 27 schools in Lebanon, aimed to assess the impact of the awareness campaign on the health knowledge and practices of 5-, 8-, and 11-year-old students throughout pre- and post-intervention testing focused on general health and healthy habits, employing 11, 14, and 15 questions tailored to 5, 8, and 11 year olds, respectively. The questions covered various aspects, including sleep, personal and dental hygiene, nutrition, physical activity, addiction, security measures, and bullying. Out of the 7100 students who participated, 16.11% (1144 students) were evaluated before and after the campaign. The results indicated a significant increase in health awareness post-intervention across all age groups. For instance, in 5-year-olds, limited awareness decreased from 91.6% to 36.38%, while adequate awareness rose from 8.03% to 62.3%. Improvement varied across health knowledge topics, with security-related questions showing the highest enhancement. Factors such as governorate, normal-weight status, and close supervision influenced improvement. However, no significant correlations were found with school type, size, gender, age, nationality, parental factors, or comorbidities. The study concludes that the school health awareness campaign successfully heightened children’s health awareness, advocating for the integration of regular health promotions into the standard educational curriculum.

A school’s commitment to promoting health extends beyond students’ efforts to encompass parental involvement and must recognize the critical role of parents in enhancing overall student well-being. This study, conducted in 27 schools across Lebanon, assessed parents’ awareness of their children’s physical and mental health. A school health campaign involved direct medical interventions on 7184 students, followed by phone interviews with 3880 parents to compare their responses with the medical findings. Discordances ranged from extreme mismatches (≥50%) to mild mismatches (<15%), with notable disparities in incomplete vaccination (67.8%), BMI (59%), and mental health indicators (expressions of sadness (69.1%), loneliness (61.0%), and anxiety (53.4%)). Factors such as school type, child’s age, governorate, family income, parents’ occupation, education level, and marital status significantly influenced discordance rates. Notably, mental health aspects exhibited higher disparities, emphasizing the need for improved communication between parents, physicians, and children. Bridging these gaps could empower parents with better knowledge, fostering environments conducive to lifelong healthy behaviors in children. The study underscores the urgency for enhanced communication strategies to bridge discrepancies and ensure a more comprehensive understanding of children’s physical and mental well-being.

Background and Objectives: Congenital abnormalities are a leading cause of neonatal morbidity and mortality and are frequently detectable through prenatal ultrasound. While widely implemented in high-income countries, such screening remains inconsistently applied in low- and middle-income regions. This study aimed to estimate the prevalence of congenital abnormalities identified via prenatal ultrasound in Lebanon and to explore associated maternal, obstetric, and psychosocial factors. Methods: A multicenter retrospective observational study, supplemented by follow-up interviews, was conducted in five Order of Malta medical centers. Pregnant women in their second trimester underwent an obstetric ultrasound, and data were collected through structured questionnaires and follow-up phone interviews. Variables included maternal demographics, obstetric history, anxiety levels (GAD-7 scores), and ultrasound findings. Results: A total of 426 pregnant women were enrolled (mean age: 28.8 ± 5.9 years). The overall prevalence of congenital abnormalities was 13.1%. Growth abnormalities were observed in 8.5% of fetuses and were significantly associated with obstetric complications and the presence of multiple abnormalities. Morphological malformations were found in 10.1% of cases and were more common among women of advanced maternal age, those with a history of anomalies, and those reporting elevated anxiety scores. Combined abnormalities, as well as growth and morphological malformations, were significantly associated with higher parity, prior anomalies, and current pregnancy complications. Conclusions: Prenatal ultrasound is essential for early detection of congenital abnormalities, facilitating timely intervention and improved neonatal outcomes. These findings emphasize the need to integrate systematic screening into prenatal care in Lebanon and for ongoing research to identify context-specific risk factors.

In this extensive study examining the health of 7184 school children aged 3 to 12 in 27 Lebanese schools, screenings involved medical evaluation and interviews, complemented by phone interviews with 3880 parents. Notably, one in two students received a medical referral, revealing prevalent issues such as dental cavities (33%), under-vaccination (25%), undetected vision problems (13%), abnormal growth (6%), underweight (27%), and overweight (33%). Additional concerns encompassed abnormal vital signs (3%), abuse signs (0.6%), infectious skin lesions (1.6%), scoliosis (1.7%), abnormal auscultation (heart 1.1%, lungs 1.2%), ear problems (3.3%), precocious puberty (0.7%), and neurologic signs (0.6%). Mental health challenges affected 20–25% of students. Public schools and Beirut exhibited higher referral rates, with girls, older children, overweight students, those lacking regular pediatrician visits, and children of self-employed or less educated parents facing elevated referral rates. In contrast, children of healthcare workers experienced fewer referrals. Against this backdrop, the study emphasizes the imperative for targeted health initiatives, particularly in marginalized areas and for socioeconomically disadvantaged students. Priority areas include dental care, weight issues, mental health, vaccination compliance, and addressing vision problems to enhance learning outcomes.

Background: Colorectal cancer (CRC) is a leading cause of cancer-related deaths worldwide, and is largely preventable through colonoscopy, during which adenomatous polyps can be detected and removed. The adenoma detection rate (ADR) and polyp detection rate (PDR) are key quality indicators of colonoscopy quality and are inversely associated with post-colonoscopy CRC. These indicators may be influenced by patient-, physician-, and procedure-related factors. This study aimed to evaluate the ADR and PDR, identify factors influencing these indicators, and compare them among gastroenterologists at a Lebanese medical center. Methods: This observational, single-center, retrospective cohort study included 257 patients aged 50–75 years who underwent first-time screening colonoscopy over 3 years. Data on patient characteristics and colonoscopy findings were collected. ADR and PDR were calculated according to established guidelines, with ADR additionally estimated using the adenoma-to-polyp detection rate quotient (APDRQ). Descriptive statistics were applied, and chi-square or Fisher’s exact tests were used to assess associations between patient-, physician-, and procedural related factors and adenoma detection. Results: Out of 257 patients, 159 had polyps detected during colonoscopy. The overall ADR was 44.4%, and the PDR was 61.8% over the three-year study period. The ADR was 52.1% in men and 38.0% in women, whereas the PDR was 68.6% in men and 56.3% in women. Although the overall ADR and PDR met or exceeded the recommended benchmarks, disparities were noted in detection rates between males and females. Bowel preparation quality and guarantor type significantly influenced adenoma detection, whereas other factors related to patients and endoscopists had no significant effect. The estimated ADRs derived from the PDRs for five endoscopists were also high, surpassing the 25% benchmark; however, their annual estimated ADRs were relatively below this threshold. Conclusion: This study provides valuable regional data and underscores the need for standardized quality monitoring and further multicentric prospective research to optimize CRC prevention in Lebanon.
