Dietary patterns and their associations with postpartum weight retention: results of the MINA cohort study.

PURPOSE: To examine the association of prepregnancy dietary patterns with postpartum weight retention at 6 months (PPWR6) among Lebanese and Qatari women. METHODS: Data for this study were derived from the Mother and Infant Nutrition Assessment (MINA) prospective cohort study conducted in Lebanon and Qatar. Pregnant women were recruited during their first trimester and were followed up for three years. For the purpose of this study, data belonging to sociodemographic characteristics of participants, prepregnancy dietary intake, prepregnancy BMI as well as weight retention at 6 months were used. Dietary intake was examined using a 98-item food frequency questionnaire. Principal component analysis was used for the derivation of dietary patterns. The associations of dietary patterns with PPWR6 were examined using simple and multiple linear regressions. RESULTS: Data was available for 177 participants (Lebanon: 93; Qatar: 84). Mean PPWR6 was 4.05 ± 5.29 kg. Significantly higher PPWR6 was observed among participants with pre-pregnancy overweight/obesity and among those with excessive gestational weight gain. Two dietary patterns were identified: the "Western" and the "Varied" patterns. After adjustment for confounders, a positive association was observed between the 'Western' pattern scores and PPWR6 (ß = 1.27; 95% CI 0.68-1.86; p value: < 0.0001). CONCLUSION: Higher adherence to the Western pattern was associated with higher PPWR6 amongst women, hence underscoring the importance of public health interventions aimed at fostering healthier dietary habits during this crucial stage of the lifecycle.

Caffeine intake and its association with nutrition, sleep, and physical activity among schoolchildren in the United Arab Emirates: a national cross-sectional study.

PURPOSE: Recent surveys indicate a significant increase in total caffeine intake among schoolchildren. Limited research has been published concerning the total intake of caffeine among schoolchildren in the Middle East and Gulf Cooperation Council (GCC) countries, including the UAE. METHODS: This cross-sectional survey estimated the total caffeine intake from foods and beverages among 10,275 schoolchildren in the UAE. Caffeine intakes were related to the European Food Safety Authority's level of no safety concern (3.0 mg/kg BW) and level of effects on sleep (1.4 mg/kg BW). RESULTS: More than half (56.2%) of the students consumed more than 100 mg (the upper limit allowed) of caffeine from dietary sources. High intake of caffeine (> 100 mg/day) was significantly associated (p = 0.001) with reduced sleep duration, difficulty falling asleep, infrequent exercising, using smart devices for more than 2 h a day, getting a lower GPA, skipping breakfast, eating fewer servings of vegetables than recommended, frequent consumption of fast food and more frequent snack consumption. CONCLUSION: Excessive intake of caffeine from different dietary sources coexists with unhealthy dietary and lifestyle behaviors and sleep problems. Tailoring educational programs and intervention strategies is warranted to correct the unhealthy intake of caffeine and the associated unhealthy dietary and lifestyle behaviors among schoolchildren in the UAE.

Food sources of fiber and micronutrients of concern among infants and young children in Lebanon: a national cross-sectional study.

BACKGROUND: Intakes of fiber, iron, zinc, calcium, vitamin D, vitamin A, and folate were shown to be low in a substantial proportion of infants and children in Lebanon. The study aims to identify the top food sources of fiber, iron, zinc, calcium, vitamin D, vitamin A, and folate amongst infants and young children in Lebanon and to evaluate the evolution of food sources of these nutrients from the beginning of the complementary feeding journey up until the age of 47.9 months. METHODS: A national cross-sectional survey was conducted in 2012 as part of the "Early Life Nutrition and Health in Lebanon" project using stratified cluster sampling. Dietary intakes for infants and young children aged 6-47.9 months (n = 763) were assessed using 24- Hour Dietary Recall. Food items were categorized into food groups and the percent contribution of each food group to nutrient intakes was determined to identify the top food sources of fiber and selected micronutrients for three age groups: 6-11.9 m (infants), 12-23.9 m (toddlers), and 24-47.9 m (preschoolers). RESULTS: The top food source of fiber was vegetables among children aged 6-47.9 months. Among infants and toddlers, infant/young child formula was the main contributor to iron, zinc, calcium, vitamin D, vitamin A, and folate intakes. Baby cereals also contributed to around 14% of iron intakes among infants. Among preschoolers, meat and fish contributed to 13% of iron intakes and 29% of zinc intakes, while cow's milk was the major contributor of calcium (41%), vitamin D (81%) and vitamin A (25%) intakes. Sweetened beverages and sweet bakery were also ranked among the major food sources contributing to substantial intakes of key nutrients, including fiber, iron, zinc, calcium, vitamin A, and folate among infants, toddlers, and preschoolers. CONCLUSIONS: In addition to milk sources, vegetables, beans and legumes, breads, meats, and rice and pasta, sweet bakery and sweetened beverages have contributed to intakes of key nutrients from early ages. This calls for implementing initiatives and designing approaches to support nutrition education and improve nutrient intakes in infancy and early childhood.

Nutrient Patterns and Bladder Cancer: A Case-Control Study in Iran.

To examine the association between nutrient patterns (NP) and the risk of bladder cancer (BC) in the Iranian population, this Hospital-based case-control study was conducted with 306 participants (106 cases and 200 controls). The cases were newly diagnosed with BC (transitional cell carcinoma). Participants' past year's dietary intake was obtained via a valid 168-item Food Frequency Questionnaire (FFQ). Principal Component Analysis was applied to derive NPs considering the intake of the nutrients. Logistic regression models were used to estimate the odds ratio (ORs) and 95%CIs. Two main NPs were obtained - Mineral Dominant (NP1) and Fat Dominant (NP2). NP1 was characterized by a high loading of folate, total carbohydrate, iron, phosphorus, fiber, total protein, magnesium, potassium, and calcium. NP2 had high loadings of trans-fatty acid (TFA), poly-unsaturated fatty acid (PUFA), total fat, saturated fatty acid (SFA), sodium, and cholesterol. Higher adherence to NP1 pattern significantly decreased the odds of BC (OR = 0.24, 95%CI: 0.09-0.67). In contrast, high adherence to NP2 resulted in almost a five-fold increase in the odds of BC (OR = 5.41, 95%CI: 2.26, 12.95). Variability in nutrient patterns has significant associations with the risk of BC, further highlighting the need to study patterns of nutrient intake rather than single nutrients.

Association between quality of sleep and screen time during the COVID-19 outbreak among adolescents in the United Arab Emirates.

The COVID-19 pandemic had a major impact on people of all ages. Adolescents' exposure to online learning is linked to excessive screen time on digital devices, which leads to poor sleep quality. This study aimed to investigate the association between screen time on different electronic devices and sleep quality among adolescents in the United Arab Emirates. This study was based on a self-reported questionnaire, which was administered online to school-aged adolescents (aged 12-19 years). The multicomponent questionnaire collected information on sociodemographic characteristics, sleep quality using the Pittsburgh Sleep Quality Index (PSQI), and screen time (minutes) on TV, TV-connected devices, laptops, smartphones, and tablets on weekdays, weeknight, and weekends using the Screen Time Questionnaire (STQ). Univariate and multivariate analyses were used to identify factors correlated with poor sleep quality. A total of 1720 adolescents were recruited from private and public schools (mean age 14.6 ± 1.97 years). The mean PSQI score was 8.09 ± 3.37, and 74.3% of participants reported poor sleep (cutoff score >5). Mean scores were highest for the sleep latency (1.85 ± 0.97) and sleep disturbance (1.56 ± 0.62) domains. The highest STQ score was observed for smartphones, with a median screen time of 420 min on weekdays and 300 min on weekends. Screen time related to smartphones on weekends (p = 0.003) and increased screen time in bed (p < 0.001) were significantly associated with poor sleep. Our results confirmed the correlation between sleep and screen time in adolescents. The results may inform educational polices that target screen time and sleep among adolescents during and after the COVID-19 pandemic.

Infant and young child feeding practices in Lebanon: a cross-sectional national study.

OBJECTIVE: To assess infant and young child feeding (IYCF) practices in Lebanon and investigate their associations with socio-demographic and lifestyle factors. DESIGN: A cross-sectional national survey was conducted in 2012-2013. In addition to a socio-demographic and lifestyle questionnaire, a 24-h dietary recall for the children was collected, with mothers as proxies. IYCF practices were assessed based on the 2021 indicators of the WHO. SETTING: Lebanon. PARTICIPANTS: Children aged 0-23 months and their mothers (n 469). RESULTS: While the majority of infants were ever breastfed (87·6 %), the prevalence of exclusive breast-feeding (BF) in those under 6 months of age was 11·0 %. Early initiation of BF was 28 %. A greater child's birth order, partner's support for BF, higher parental education, maternal BF knowledge and non-smoking were associated with higher odds of meeting BF recommendations. As for complementary feeding, 92·8 % of children (6-23 months) met the minimum meal frequency indicator, 37·5 % met the minimum dietary diversity (MDD) and 34·4 % met the minimum adequate diet (MAD). The consumption of unhealthy food was observed amongst 48·9 % of children, with nearly 37 % consuming sweet beverages. Older maternal age and maternal overweight/obesity were associated with lower odds of meeting MDD and MAD, while child's age and partner's support for BF were associated with higher odds. CONCLUSIONS: The results documented suboptimal IYCF practices amongst Lebanese children and identified a number of factors associated with these practices. Findings from this study will help guide the development of culture-specific programmes aimed at improving IYCF practices in Lebanon.

Sustainable diets among youth: Validity and reliability of a questionnaire assessing knowledge, attitudes, practices, and willingness to change.

BACKGROUND: In light of the global commitment to promoting sustainable dietary choices and the pivotal role of young adults in the adoption of these choices, it is paramount to understand their perspectives of healthy and sustainable diets. The present study aimed to investigate the validity and reliability of a questionnaire examining the knowledge, attitudes, practices, and willingness to change regarding sustainable diets among young adults in the United Arab Emirates (UAE). METHODS: Male and female students attending University of Sharjah, UAE (n = 436), completed an online questionnaire consisting of four sections: knowledge, attitudes, practices, and willingness to change with regard to sustainable diets. Of the participants, 106 completed the questionnaire a second time, 1 month later. Factor analysis (FA) (both exploratory and confirmatory), Cronbach-α, interitem correlations, and intra class correlation (ICC) coefficients were used in the data analysis. RESULTS: Exploratory FA revealed four factors corresponding to the components of the questionnaire. Results of the confirmatory FA indicated a good fit: the χ2 df ratio was < 5 (2.3), root mean squared error of approximation was < 0.08 (0.048) and the comparative fit index was above 0.9 (0.901). Cronbach α and interitem correlations were: knowledge: 0.57 and 0.21; attitude: 0.70 and 0.28; practices: 0.76 and 0.39; willingness to change: 0.69 and 0.27. The ICC coefficients, assessing the reliability of the questionnaire, ranged between 0.48 and 0.92 for the various items. CONCLUSIONS: The developed questionnaire is a valid and reliable tool that could be used to identify the gaps and opportunities for the development of evidence-based interventions aiming to enhance the uptake of sustainable diets among young adults.

A Status Review on Health-Promoting Properties and Global Regulation of Essential Oils.

Since ancient times, essential oils (EOs) have been known for their therapeutic potential against many health issues. Recent studies suggest that EOs may contribute to the regulation and modulation of various biomarkers and cellular pathways responsible for metabolic health as well as the development of many diseases, including cancer, obesity, diabetes, cardiovascular diseases, and bacterial infections. During metabolic dysfunction and even infections, the immune system becomes compromised and releases pro-inflammatory cytokines that lead to serious health consequences. The bioactive compounds present in EOs (especially terpenoids and phenylpropanoids) with different chemical compositions from fruits, vegetables, and medicinal plants confer protection against these metabolic and infectious diseases through anti-inflammatory, antioxidant, anti-cancer, and anti-microbial properties. In this review, we have highlighted some targeted physiological and cellular actions through which EOs may exhibit anti-inflammatory, anti-cancer, and anti-microbial properties. In addition, it has been observed that EOs from specific plant sources may play a significant role in the prevention of obesity, diabetes, hypertension, dyslipidemia, microbial infections, and increasing breast milk production, along with improvements in heart, liver, and brain health. The current status of the bioactive activities of EOs and their therapeutic effects are covered in this review. However, with respect to the health benefits of EOs, it is very important to regulate the dose and usage of EOs to reduce their adverse health effects. Therefore, we specified that some countries have their own regulatory bodies while others follow WHO and FAO standards and legislation for the use of EOs.

Association of Recommended and Non-Recommended Food Score and Risk of Bladder Cancer: A Case-Control Study.

Bladder cancer (BC) is the ninth most common cancer in the world. Dietary patterns and diet quality could reduce exposure to carcinogenic factors postulated to increase the risk of BC. The main objective of this study was to investigate the associations of Recommended Food Score (RFS) and Non-Recommended Food Score (n-RFS) with the risk of BC among Iranian adults.This is a hospital-based case-control study, conducted at three referral hospitals in Tehran, the capital of Iran. Cases consisted of 103 histologically confirmed BC patients, aged greater than 45 years. Age-matched controls (n = 200) were selected from the same hospital where cases were recruited. Controls were patients with non-neoplastic diseases that are not related to smoking, or long-term diet modification. Dietary intake was assessed by a 168-item Food Frequency Questionnaire (FFQ), which was validated in Iran. Logistic regression tests were used to estimate the relationship between RFS and n-RFS with BC.The risk of BC decreased by 69% (OR = 0.31; 95% CI:0.13-0.71) among participants belonging to the highest compared with the lowest quartile of RFS. After adjusting for age, sex, smoking, and total energy, a significant inverse trend was observed between the risk of BC and quartile of RFS. Regarding the n-RFS, also expressed as quartiles, subjects in the fourth quartile were at 2.7 times higher risk of having BC compared to participants in the first quartile (OR = 2.7; 95%CI: 1.07-6.78).The findings of this study suggested that, adherence to RFS decreased the risk of BC. Additionally, a higher score of n-RFS may lead to an increased risk of BC. These findings could be used to develop evidence-based recommendations for the prevention of BC in Iran.

Adherence to the Mediterranean diet during pregnancy is associated with lower odds of excessive gestational weight gain and postpartum weight retention: results of the Mother-Infant Study Cohort.

During the first 1000 d of life, gestational weight gain (GWG) and postpartum weight retention (PPWR) are considered critical determinants of nutritional status. This study examined the effect of adherence to the Mediterranean diet (MD) during pregnancy on GWG and PPWR at 2 and 6 months among women in the United Arab Emirates (UAE), using data from the Mother-Infant Study Cohort. The latter is a prospective study, for which pregnant women were recruited (n 243) during their third trimester and were followed up for 18 months. Data on socio-demographic characteristics and anthropometric measurements were obtained. An eighty-six-item FFQ was used to examine dietary intake during pregnancy. Adherence to the MD was assessed using the alternate MD (aMED) and the Lebanese MD (LMD). Adherence to the MD, PPWR2 (2 months) and PPWR6 (6 months) were considered high if participants belonged to the third tertile of the respective measures. Results indicated that 57·5 % of participants had excessive GWG while 50·7 % and 45 % retained ≥ 5 kg at 2 and 6 months postpartum, respectively. After adjustment, adherence to both MD scores was associated with lower odds of excessive GWG (aMED, OR:0·41, 95 % CI:0·18, 0·93; LMD, OR:0·40, 95 % CI: 0·16, 0·98). Adherence to MD was also associated with PPWR2 (aMED: OR: 0·23, 95 % CI: 0·06, 0·88) and PPWR6 (aMED OR:0·26; 95 % CI:0·08-0·86; LMD, OR:0·32; 95 % CI: 0·1, 0·98). The findings of this study showed that adherence to the MD may reduce GWG and PPWR and, hence, underscored the importance of promoting the MD for better health of the mother and infant.

Adherence to the Mediterranean diet and its association with environmental footprints among women of childbearing age in the United Arab Emirates.

PURPOSE: To examine the association of adherence to the Mediterranean Diet (MD) with Environmental Footprints (EFPs) among women of childbearing age in the United Arab Emirates (UAE). METHODS: Data belonging to a nationally representative sample of 482 women (19-50 years) were derived from a previous survey in the UAE. In face-to-face interviews, participants completed questionnaires addressing sociodemographic, physical activity, and dietary intake characteristics; the latter assessed using a multiple pass 24-h recall. The composite Mediterranean (c-MED) index was used to examine the adherence to the MD. Metrics for the EFPs (water use, energy use, and GHG emissions) were calculated using Life Cycle Analyses. Descriptive statistics and linear regressions were used in data analysis. RESULTS: In the study sample, the distribution of the c-MED scores was skewed to the right, indicating a low adherence to the MD. The lowest contributions to the total c-MED score were observed for legumes (2.9%) and olive oil (1.8%). The EFPs associated with food consumption per 1000 kcal were: water use: 1256.89 ± 544.95 L/day; energy use: 18.01 ± 7.85 MJ/day, and GHG: 2.46 ± 1.46 kg CO2 eq/day. After adjustment for age, energy intake, and potential confounders, being adherent to the MD was associated with 540.57 [95% CI (- 726.6; - 354.54)] units decrease in water use and 0.94 units decrease in GHG emissions [95% CI (- 1.45; - 0.43)]. CONCLUSIONS: The findings of this study revealed an inverse association between adherence to the MD and EFPs. As such, the MD may represent a promising dietary strategy to improve health outcomes and reduce the environmental impact. Public health programs addressing the low adherence to the MD among women of childbearing age in the UAE are warranted.

Food consumption patterns and nutrient intakes of infants and young children amidst the nutrition transition: the case of Lebanon.

BACKGROUND: This is the first study on dietary intakes of infants and young children in the Eastern Mediterranean Region, a region that is currently witnessing the nutrition transition. It aims at characterizing food consumption patterns amongst 0-4 year old children in Lebanon, evaluating their macro- and micronutrient intakes and assessing adherence to dietary recommendations. METHODS: Based on a national cross-sectional survey in 2012 (n = 866), the study collected data on sociodemographic and anthropometric characteristics, and one 24-hour dietary recall was administered. Nutrient intakes were compared with reference values: Estimated Average Requirement (EAR), Adequate Intake (AI) and Acceptable Macronutrient Distribution Range (AMDR). RESULTS: Milk was the highest contributor to energy intake (EI) in infants (95.8 and 56.5% in 0-5.9 months and 6-11.9 months old infants, respectively), while its intake was lower among toddlers and preschoolers (35.4 and 15.1%, respectively). In contrast, intakes of sweets and sweetened beverages were the highest in preschoolers compared to younger children, contributing 18.5% EI in preschoolers. Compared to dietary guidelines, the lowest dietary adherence was found for vegetables (17.8-20.7%) and fruits (14.4-34.3%). Protein intake was within the recommendations for the vast majority of children. Although total fat intake was lower in toddlers and preschoolers compared to infants, more than 40% of toddlers and preschoolers exceeded the AMDR for fat and 87.3% of preschoolers exceeded the upper limit for saturated fat. Only 3.6% of toddlers and 11.5% of preschoolers exceeded the AI level for dietary fiber. Micronutrient intake assessment showed that mean intakes in infants exceeded the AI for all micronutrients, except for vitamin D and magnesium. In toddlers, vitamin D and calcium were below the EAR among 84.7, and 44.6%, respectively. In preschoolers, most of the children (91.9%) had inadequate intakes of vitamin D, and a third had inadequate intakes of folate, calcium and vitamin A. CONCLUSIONS: This study identified priority issues for nutrition intervention in infants and young children in Lebanon. Concerted multi-stakeholder efforts are needed to instill heathier food consumption and nutrient intake patterns early in life.

Association of Dietary Approaches to Stop Hypertension diet and risk of bladder cancer: A case-control study.

OBJECTIVE: The Dietary Approaches to Stop Hypertension (DASH) diet is rich in recommended foods that are inversely associated with bladder cancer (BC) risk. The main objective of this study was to investigate the association between adherence to DASH diet and the risk of BC among Iranian adults. METHOD: This study included 103 BC cases and 200 controls. The controls were patients who were hospitalised for acute non-neoplastic diseases. DASH scores were computed from dietary intake assessed by a previously validated food frequency questionnaire. RESULTS: After controlling for potential confounders, participants in the highest quintile of DASH (compared to the lowest quintile) had 84% lower BC risk (OR = 0.16; 95%CI: 0.05-0.45; p trend = 0.001). Among the DASH components, significant negative associations were observed between low fat dairy and whole grains intake with BC (p value < 0.05). A positive relation was observed for sodium, nuts and legumes, and sweetened beverages (p value < 0.05). CONCLUSION: The results of this study suggested that adherence to DASH might be associated with reduced risk of BC. These findings could be used to develop evidence-based recommendations for the prevention of BC.

Food and nutrient intake of school-aged children in Lebanon and their adherence to dietary guidelines and recommendations.

BACKGROUND: Lebanon, an Eastern Mediterranean country, is witnessing a remarkable nutrition transition, and the diets of school-aged children may be amongst those most affected. However, limited studies have examined the food consumption patterns and nutrient adequacy in this age group. OBJECTIVES: The present study aimed to evaluate the dietary intakes of school-aged children in Lebanon and assess their adherence to nutrition guidelines and recommendations. METHODS: This study used data for 4-13 y-old children (n = 711) from a national cross-sectional survey conducted in 2014-2015 on a representative sample of Lebanese households with children. Dietary intake was assessed using single 24-h recall method. Estimated food group and nutrient intakes were compared to dietary recommendations and age-specific dietary reference intakes (DRI), including Estimated Average Requirements (EAR) and Acceptable Macronutrient Distribution Range (AMDR). Food group, energy, macro- and micro-nutrient intakes were presented for all children in the sample and stratified by age (4-8 y and 9-13 y) and sex. RESULTS: Mean energy intake of 4-13-year-old children was 1804 kcal/d. Almost half of the energy was provided by carbohydrates while 12% of children had protein intakes below EAR. Approximately three-quarters of children (4-13 y) exceeded the AMDR for total fat and saturated fats, and a similar proportion over consumed added sugars. The main sources of energy intake (EI) among children were the sweets, sweetened beverages and desserts followed by grains and mixed dishes. No significant differences were noted in %EI from different food groups, by sex, in either age groups. The highest adherence of children to food group recommendations was observed for the grains' food group (47.2-54.4%EI), while the lowest adherence was found for vegetables (3.1-14.1%EI). A high prevalence of vitamin and mineral inadequacies was noted amongst 4-13 y old children for key micronutrients, including vitamin D (99%), calcium (81%), and vitamin A (69.5%). Risk of inadequate micronutrient intakes was significantly increased among the older age group (p-value < 0.05). CONCLUSION: Nutrient intakes of school-aged children in Lebanon reflect suboptimal nutrition. Educational and public health interventions are needed to promote healthier diets among children and prevent micronutrient deficiencies during this critical phase.

Diets and dietary supplements used during the COVID-19 pandemic in the United Arab Emirates: A cross-sectional survey.

INTRODUCTION: Since the beginning of the Coronavirus disease 2019 (COVID-19) pandemic, there has been a marked increase in the use of diets and dietary supplements (DDS) for the prevention and treatment of this emerging disease. While DDS are generally regarded as harmless, little evidence exists on the safety and efficacy of their use for COVID-19. OBJECTIVES: To investigate the pattern and determinants of DDS use among the United Arab Emirates (UAE) population for the prevention and treatment of COVID-19. DESIGN: Cross-sectional web-based survey. SETTING: Adults residing in the UAE. PARTICIPANTS: Participants (n = 2,060) residing in the UAE were recruited from databases of the Supreme Council for Family Affairs - Sharjah networks in the various Emirates. PRIMARY AND SECONDARY OUTCOMES: Prevalence and determinants for the use of different DDS for the prevention and treatment of COVID-19 in the UAE, and sources of information for DDS use. RESULTS: The majority of participants reported using a form of the DDS understudy, with special foods being the most common (95.5%), followed by intake of citrus fruits (62.1%), supplements use (56.6%), increased water intake (50%), and herbal teas (38.4%). Only 20% of participants reported the main source of information on DDS to be health care practitioners, with the majority relying on either social media (40.4%) or family and friends (28.7%). After adjustment, female gender, older age (>40 years), and Asian ethnicities were characteristics associated with higher odds of using most of the DDS modalities and were also correlates of reporting health care practitioners as the main source of information for their DDS use. CONCLUSIONS: The findings showed widespread use of DDS for the prevention and treatment of COVID-19. The use of DDS in this study was mainly guided by social media with a marginal role of health care practitioners. These findings call for a more integrative approach towards DDS to ensure its proper and safe use.

Nutrition and Breast Cancer Research in Arab Countries: Gaps, Opportunities, and Recommendations.

According to the WHO, Arab countries have the highest relative increase in Breast Cancer (BC) rates worldwide. Current shifts in dietary patterns in these countries are postulated as important modifiable risk factors of the disease. The objectives of this review were to examine the gaps and opportunities in the extent, range and nature of nutrition-related BC research in Arab countries. Studies (n = 286) were identified through searching 14 electronic databases. Among the gaps identified were limited international collaborations, preponderance of laboratory-based research at the expense of population-based research, focus on single supplement/nutrient/food research, limited use of dietary assessment tools, and studying nutrition in isolation of other environmental factors. Despite these gaps, several opportunities appeared. The distribution of papers among Arab countries suggested that collaboration between high and middle income countries could create a positive synergy between research expertise and wealth. In addition, the steady increase in the number of articles published during the last two decades reflected a promising momentum in nutrition and BC research in the Arab world. These gaps and opportunities constituted context-specific evidence to orient nutrition and BC research in Arab countries which could ultimately lead to development of effective interventions for prevention of BC in these countries.

Gaussian Graphical Models Identified Food Intake Networks among Iranian Women with and without Breast Cancer: A Case-Control Study.

BACKGROUND: Dietary patterns may be an important predictor of breast cancer risk. However, they cannot completely explain the pairwise correlations among foods. The purpose of this study is to compare food intake networks derived by Gaussian Graphical Models (GGMs) for women with and without breast cancer to better understand how foods are consumed in relation to each other according to disease status. METHODS: A total of 134 women with breast cancer and 267 hospital controls were selected from referral hospitals of Tehran, Iran. Dietary intakes were evaluated by using a validated 168 food-items semi-quantitative food frequency questionnaire. GGMs were applied to log-transformed intakes of 28 food groups to construct outcome-specific food networks. RESULTS: Among cases, a main network containing intakes of 12 central food groups (vegetables, fruits, nuts and seeds, olive oil and olive, processed meat, sweets, salt, soft drinks, fried potatoes, pickles, low-fat dairy, pizza) was detected. In controls, a main network including six central food groups (liquid oils, vegetables, fruits, sweets, fried potatoes and soft drinks) was identified. CONCLUSIONS: The findings of this study revealed a difference in GGM-identified networks graphs between cases and controls. Overall, GGM may provide additional understanding of relationships between diet and health.

Erosion of the Mediterranean diet among adolescents: evidence from an Eastern Mediterranean Country.

At a time when the health benefits of the Mediterranean diet (MD) are pervasively recognised, a paradoxical observation is the decreasing adherence to this dietary pattern in its native countries. This study aims to investigate temporal trends in adherence to the MD among adolescents (10-19 years old) in Lebanon. Data were drawn from three national cross-sectional surveys conducted at three points in time: 1997 (n 2004), 2009 (n 3656) and 2015 (n 1204). Dietary intake was assessed using 24-h dietary recalls, and adherence to the MD was assessed using two country-specific indexes: the composite Mediterranean diet (c-MED) index and Lebanese Mediterranean diet (LMD) index. Significant decreases in c-MED and LMD scores and in the proportion of adolescents adhering to the MD were observed between 1997 and 2015, with more consistent results among females (P < 0·05). Projections for the year 2030 showed further decreases, with less than a quarter of adolescents remaining adherent to the MD. Based on linear regression analyses, belonging to the year 2009 was associated with significantly lower MD scores compared with 1997, even after adjustment for potential covariates (c-MED ß = -0·16, 95 % CI -0·30, -0·01; LMD ß = -0·42, 95 % CI -0·67, -0·17). Similar results were obtained when comparing survey year 2015 with 1997 (c-MED score ß = -0·20, 95 % CI -0·33, -0·06; LMD score ß = -0·60, 95 % CI -0·82, -0·37). Findings highlight the erosion of the MD among Lebanese adolescents and underline the need for a comprehensive food system approach that fosters the promotion of the MD as a nutritionally balanced and sustainable dietary pattern.

Impact of coronavirus 2019 on mental health and lifestyle adaptations of pregnant women in the United Arab Emirates: a cross-sectional study.

BACKGROUND: In light of the pandemic, pregnant women are particularly vulnerable to increased psychological distress and in need of imperative preventive measures. This study aimed to investigate the impact of the pandemic on mental health, lifestyle adaptations, and their determinants among pregnant women in the United Arab Emirates. METHODS: A survey was conducted electronically between June and August 2020. Pregnant women were recruited from prenatal clinics in the UAE and invited to participate in an online survey developed on Google Forms. The questionnaire included socio-demographic characteristics, the Impact of Event Scale- Revised, the Perceived Support Scale and lifestyle-related factors. RESULTS: A total of 384 pregnant women completed the questionnaire of whom 20.6% were in their 1st trimester, 46.1% in their 2nd and 33.3% in their 3rd trimester. The mean IES-R score for the respondents was 26.15 ± 13.55, corresponding to a mild stressful impact, which did not differ significantly among trimesters of pregnancy. Pregnant women expressed increased stress from staying home (64%), work (40%), feeling frightened (66%) and apprehensive (59%). Women reported increased support and sharing their feelings with family members (59%), mainly in the 1st and 3rd trimester of pregnancy (P < 0.05). There was a greater attention to mental health (48%), resting time (55.3%), and relaxing time (57.3%); while a decreased amount of time was spent engaging in physical activities (53.6%), which differed significantly between trimesters (P = 0.02). CONCLUSIONS: The COVID-19 pandemic was associated with a mild stressful impact among pregnant women in the UAE, braced by strong family support and self-care mental health behaviors.

Practices and resilience of dieticians during the COVID-19 pandemic: a national survey in the United Arab Emirates.

BACKGROUND: The COVID-19 pandemic impacted the practices and resilience of most healthcare workers, including dieticians. In addition to offering critical care to COVID-19 patients, dieticians play a major role in preventing and managing conditions known to affect COVID-19, such as obesity and metabolic disorders. The objective of this study was to examine the conditions and changes in the work environment as well as resilience and its correlates among dieticians during the COVID-19 pandemic in the United Arab Emirates (UAE). METHODS: A cross-sectional national survey was conducted among dieticians practicing in the UAE (n = 371), using a web-based questionnaire. The questionnaire addressed, in addition to the sociodemographic information, the practice-related characteristics and resilience of participants. For the latter the Connor-Davidson Resilience Scale© was used. Descriptive statistics as well as simple and multiple linear regressions were used in the statistical analysis. RESULTS: Of participants, 26.4% reported not having access to personal protective equipment and 50% indicated being concerned for their safety and health. Furthermore, considerable proportions of participants were not satisfied (45%) with the support nor with the appreciation (37.7%) they received during the pandemic. One in four dieticians considered quitting his/her job. While 65.8% of participants reported counseling COVID-19 patients, a third did not use any online platform for counseling. The most cited challenge to dietetic practice during the pandemic was 'maintaining work-life balance' (43.1%). The mean CD-RISC score was 72.0 ± 14.0. After adjustment, working in a hospital or public clinic (as opposed to private clinic), having a condition preventing face-to-face counseling, considering quitting job and feeling neutral or dissatisfied with the appreciation were associated with lower resilience scores, while counseling COVID-19 patients was associated with higher scores. CONCLUSIONS: Despite the fairly high resilience among dieticians practicing in the UAE during the COVID-19 pandemic, the findings of this study highlighted a few challenges, mainly related to safe practice environment, support for online counseling, and maintaining work-life balance. Concerted efforts of policy and decision makers ought to develop targeted programs for dieticians to ensure their retention and wellbeing during the COVID-19 pandemic.
