Dietary habits and Helicobacter pylori infection: a cross sectional study at a Lebanese hospital.

BACKGROUND: To examine the association between dietary habits and Helicobacter pylori (H. pylori) infection among patients at a tertiary healthcare center in Lebanon. METHODS: This cross-sectional study was conducted on 294 patients in 2016, at a hospital in Northern Lebanon. Participants were interviewed using a structured questionnaire to collect information on socio-demographic and lifestyle characteristics; dietary habits were ascertained via a short food frequency questionnaire (FFQ). H. pylori status (positive vs. negative) was determined after upper GI endoscopy where gastric biopsy specimens from the antrum, body, and fundus region were collected and then sent for pathology analysis. Multivariable logistic regression was conducted to identify the association between socio-demographic, lifestyle, dietary and other health-related variables with H pylori infection. RESULTS: The prevalence of H. pylori infection was found to be 52.4% in this sample. Results of the multivariable analysis showed that H. pylori infection risk was higher among participants with a university education or above (OR = 2.74; CI = 1.17-6.44), those with a history of peptic ulcers (OR = 3.80; CI = 1.80-8.01), gastric adenocarcinoma (OR = 3.99; CI = 1.35-11.83) and vitamin D level below normal (OR = 29.14; CI = 11.77-72.13). In contrast, hyperglycemia was protective against H. pylori (OR = 0.18; CI = 0.03-0.89). No relationship between dietary habits and H. pylori infection was found in the adjusted analysis. CONCLUSIONS: Socio-demographic and clinical variables are found to be associated with H. pylori, but not with dietary factors. Further studies are needed to investigate the effect of diet on H. pylori risk.

Potential use of telephone surveys for non-communicable disease surveillance in developing countries: evidence from a national household survey in Lebanon.

BACKGROUND: Given the worldwide proliferation of cellphones, this paper examines their potential use for the surveillance of non-communicable disease (NCD) risk factors in a Middle Eastern country. METHODS: Data were derived from a national household survey of 2,656 adults (aged 18 years or older) in Lebanon in 2009. Responses to questions on phone ownership yielded two subsamples, the 'cell phone sample' (n = 1,404) and the 'any phone sample' (n = 2,158). Prevalence estimates of various socio-demographics and 11 key NCD risk factors and comorbidities were compared between each subsample and the overall household sample. RESULTS: Adjusting for baseline age and sex distribution, no differences were observed for all NCD indicators when comparing either of subsamples to the overall household sample, except for binge drinking [(OR = 1.55, 95 % CI: 1.33-1.81) and (OR = 1.48, 95 % CI: 1.18-1.85) for 'cell phone subsample' and 'any phone subsample', respectively] and self-rated health (OR = 1.23, 95 % CI: 1.10-1.36) and (OR = 1.16, 95 % CI: 1.02-1.32), respectively). Differences in the odds of hyperlipidemia (OR = 1.27, 95 % CI: 1.06-1.51) was also found in the subsample of 'any phone' carriers. CONCLUSIONS: Multi-mode telephone surveillance techniques provide viable alternative to face-to-face surveys in developing countries. Cell phones may also be useful for personalized public health and medical care interventions in young populations.

Determinants of exclusive breastfeeding in an urban population of primiparas in Lebanon: a cross-sectional study.

BACKGROUND: The proportion of mothers who exclusively breastfeed their babies up to 6 months remains low. Determinants of breastfeeding practices have been largely documented in high-income countries. Little evidence exists on possible predictors of breastfeeding behaviors in the Middle East. Our aim was to assess the prevalence of breastfeeding in Beirut and determine the factors that impact breastfeeding behavior in this population. METHODS: Data for this longitudinal study is nested within a randomized controlled trial (RCT) assessing the impact of a 24-hour hotline and postpartum support film on postpartum stress. Healthy first-time mothers delivering in the capital Beirut between March and July 2009, were interviewed at 1-3 days and 8-12 weeks post delivery. A multiple logistic regression analysis was used to determine the factors associated with exclusive breastfeeding at 8-12 weeks postpartum. RESULTS: The overall breastfeeding rate at 8-12 weeks postpartum was 67%. The exclusive breastfeeding rate was 27.4%. Factors associated with exclusive breastfeeding included maternal work (OR=3.92; p-value<0.001), planned pregnancy (OR=2.42, p-value=0.010), intention to breastfeed (OR=3.28; p-value=0.043), source of maternal emotional support (OR=1.87, p-value=0.039) and the use the postpartum support video, the hotline service or both (OR=2.55, p-value=0.044; OR=3.87, p-value=0.004 and OR=4.13, p-value=0.003). CONCLUSIONS: The proportion of healthy first-time mothers who exclusively breastfeed in Beirut is extremely low. Factors associated with breastfeeding behavior are diverse. Future research and interventions should target different levels of the maternal-child pair's ecosystem. TRIAL REGISTRATION: ClinicalTrials.gov, NCT00857051.
