RESUMEN

Objective The association between sleep quality and overall health has been extensively examined. However, few studies have investigated the relationship between sleep and the inflammatory potential of the diet. Thus, the purpose of the present study was to explore the association between the scores on the Energy-Adjusted Dietary Inflammatory Index (E-DII) and sleep quality in Lebanese university students. Materials and Methods We conducted a cross-sectional study with students attending the Tripoli campus of Beirut Arab University. A total of 270 students aged between 17 and 25 years were randomly selected. All students filled out a multicomponent questionnaire that included an assessment of their sleep quality using the Pittsburg Sleep Quality Index, and of their physical activity level using the short version of the International Physical Activity Questionnaire. The scores on the E-DII were calculated based on a validated food frequency questionnaire. Results Individuals in the highest (most proinflammatory) quartile of the E-DII were at an increased risk of having poor overall sleep quality compared with the lowest quartile (odds ratio [OR] = 2.86; 95% confidence interval [95%CI]: 1.27-6.44). Regarding the individual domains of sleep quality, subjects in quartiles 3 and 4 of the E-DII were at an increased risk of having poor sleep efficiency compared with those in quartile 1 (OR = 2.49; 95%CI: 1.12-5.54; and OR = 2.52, 95%CI: 1.13-5.62 respectively). However, individuals in quartile 3 were at a reduced risk of having daytime dysfunction compared with those in the lowest quartile (OR = 0.44; 95%CI: 0.23-0.83). Conclusion The inflammatory potential of the diet seems to be related to sleep quality in our sample of Lebanese university students. Future prospective studies are required to further explore this association.

RESUMEN

BACKGROUND: A number of physical, emotional, cognitive and psychological changes shape the adolescence phase, which may influence health and well-being. Therefore, it is important to develop healthy eating habits that will persist into adulthood. OBJECTIVE: This study was conducted in order to investigate in depth the association between components of the Mediterranean diet (MD) and health-related quality of life (HRQoL), along with its different subscales, among Lebanese adolescent students attending schools in Tripoli, North Lebanon. METHODS: A cross-sectional survey was undertaken among 798 teenagers aged 11 to 18. All responded to a questionnaire that evaluated their HRQoL, sociodemographic characteristics and adherence to the Mediterranean diet. RESULTS: The results of the study revealed that only 15.9% of the students had a high adherence to the MD. With regard to the components of the MD associated with the HRQoL, it was revealed that fruit intake by the students (once daily) was associated with a better general well-being (P = 0.047). In addition, fish consumption (two to three times per week) and daily intake of a dairy product for breakfast were positively associated with the total KIDSCREEN score (P < 0.001 and P = 0.003, respectively). Finally, skipping breakfast was correlated with a poorer general well-being (P = 0.013). CONCLUSION: Our results suggest a strong correlation between MD adherence and HRQoL in Lebanese adolescents. However, future studies are warranted in order to strengthen the evidence of this association.

RESUMEN

Background and Aim: Toxoplasmosis is a disease caused by the protozoan parasite Toxoplasma gondii that affects both humans and animals, leading to abortions and significant clinical manifestations in pregnant and immunocompromised hosts, in addition to massive economic losses in animal industries. Data from Lebanon are scarce regarding the seroprevalence of T. gondii infection in livestock. This study aimed to estimate the seroprevalence and assess the associated risk factors of T. gondii infection in sheep and goats in Lebanon. Materials and Methods: A cross-sectional study was carried out from May 2020 to April 2021. Blood samples from 150 sheep and 145 goats (total 295) destined for human consumption were obtained from 20 Lebanese farms located in the North and Beqaa governorates. The anti-T. gondii immunoglobulin G antibodies were assayed through means of a modified agglutination test with a cutoff titer of 20. Results: An overall seroprevalence of 48.5% (143/295) was reported: About 56.6% seroprevalence was found in sheep (85/150) and 40% (58/145) in goats. Adult age, female gender, and the wet season were significantly associated with an increased seropositivity rate of T. gondii infection (p < 0.001, p = 0.001, and p = 0.043, respectively). Conclusion: These results confirm the spread of T. gondii in sheep and goats destined for human consumption in various geographical regions in Lebanon. Therefore, continuous monitoring of T. gondii infection in livestock is warranted to control the spread of the infection and limit its potential transmission to humans through the consumption of raw or undercooked meat.

RESUMEN

The Mediterranean diet (MD) is a model of a healthy diet and healthy lifestyle. Adherence to the MD has been correlated with a reduction in many metabolic disorders including cancers. The factors associated with adolescents' adherence to the MD in North Lebanon using the KIDMED index have never been explored. Therefore, we thought to examine these factors amongst a sample of them. A cross-sectional survey was conducted in the city of Tripoli, North Lebanon. A total of 798 adolescents aged 11-18 years were randomly selected to participate in this study. All participants completed a questionnaire assessing adherence to the MD (KIDMED index), physical activity (physical activity questionnaires for older children and adolescents), health-related quality of life (KIDSCREEN-27 index) and sociodemographic characteristics (age, sex, grade level and parents' educational status). Anthropometric measurements, including weight, height and waist circumference, were also collected. Adherence to the MD was good amongst only 13·3 % of the adolescents. The prevalence rate of overweight and obesity was elevated, affecting 36·9 % of the students. Lower adherence to the MD was significantly correlated with skipping meals (P = 0·001). Meanwhile, adolescents who were engaged in a high level of physical activity, those who consumed more meals with their families and those who benefited from better physical well-being had a better diet quality (P < 0·001). Nutrition intervention programmes, as well as public health policies, would be of interest in order to improve diet quality amongst Lebanese adolescents.

RESUMEN

OBJECTIVE: The purpose of this cross-sectional study was to investigate the association between sociodemographic factors, health-related characteristics, functional status and oral health-related quality of life (OHRQoL) among a representative sample of the community-dwelling Lebanese elderly. METHODS: The study sample included 905 randomly selected community-dwelling elderly Lebanese aged 65 or older living in Greater Beirut. The sample was selected through multi-stage cluster sampling. Participants completed a comprehensive multi-component questionnaire, administrated by trained interviewers, including sociodemographic factors, health characteristics, eating behaviours and functional characteristics. OHRQoL was assessed through the Geriatric Oral Health Assessment Index (GOHAI) questionnaire. RESULTS: Among the participants, 51.6% reported poor OHRQoL. The following variables were significantly associated with poor OHRQoL: lack of health insurance (OR = 1.72, 95% CI: 1.05-2.81); poor or average self-rated general health (OR = 2.58, 95% CI: 1.23-5.41 and OR = 2.27, 95% CI: 1.24-4.16, respectively); monotony of diet (OR = 1.69, 95%CI: 1.02-2.79); absence of dentures (OR = 13.78, 95% CI: 5.02-37.84); insufficient dentures (OR = 18.19, 95%CI: 4.43-74.68); presence of dentures (OR = 2.18, 95%CI: 1.16-4.09); and depression (OR = 2.21, 95%CI: 1.26-3.89). CONCLUSION: The present study revealed that a lack of health insurance, negative perception of general health, monotony of diet, denture use and depression were significantly correlated with poor OHRQoL among community-dwelling Lebanese elderly.

RESUMEN

Background: The implications of rapid aging of the Lebanese population are under-researched. No national studies have so far investigated the living conditions and the health status of urban Lebanese elderly across gender. This was a cross-sectional study involving 905 randomly selected community dwelling elderly aged ≥65 years living in Greater Beirut. Gender differences were assessed among participants who completed a standardized questionnaire on socio-demographic factors, nutritional, health, and functional characteristics. The sample included 533 men (59%) and 372 women (41%). Elderly were regrouped into 'younger elderly' (≤70 years), and 'older elderly' (>70 years) which represented respectively 44.3% and 55.7% of the total population. Women, regardless of their age, were less educated and more likely to live alone. Moreover, poor nutritional status, self-perceived health, absence of physical activity, comorbidity, polymedication and depression were significantly higher among women. 'Older elderly' women became significantly more functionally disabled compared with men of their age. This study evidenced that Lebanese elderly women were disadvantaged regarding their socio-economic, health and functional status. It is requested a nationwide effort to improve the socio-economic status and the health of Lebanese elderly, especially women.

RESUMEN

AIM: To assess the nutritional status, and its association with sociodemographic factors, health and functional status of community-dwelling older adults living in the Greater Beirut area. METHODS: This was a cross-sectional study involving 905 randomly selected community dwelling older adults aged ≥65 years living in Greater Beirut (Beirut and surrounding suburbs). Participants completed a standardized questionnaire on sociodemographic factors, health characteristics, and functional and nutritional status, based on the Mini Nutritional Assessment. RESULTS: Among the older adults who participated in the study, 2.8% (95% CI 0.01-0.03) were malnourished, and 45.5% (95% CI 0.42-0.48) were at risk of malnutrition. Sociodemographic variables were not associated with the nutritional status. Variables significantly associated with poorer nutritional status were: poor perception of general health (OR 1.58, 95%CI 1.28-1.97), more chronic diseases (OR 2.05, 95% CI1.26-3.33), poor perception of oral health (OR 1.36, 95% CI 1.14-1.61), depressive disorders (OR 1.76, 95% CI 1.30-2.40), higher body mass index (OR 1.98, 95% CI1.67-2.34) and disability (OR 5.80, 95% CI 1.96-17.11). CONCLUSIONS: The present study showed an unacceptable risk of malnutrition among Lebanese older adults, independent of age, sex and socioeconomic status. The presence of comorbidities, treated or not, affecting general and oral health emerged as major determinants of poor nutrition. Geriatr Gerontol Int 2017; 17: 424-432.
