Vitamin D status and its relationship with obesity indicators in Moroccan adult women.

Background: Although vitamin D deficiency has been studied in various populations, there are few data on its prevalence and associated factors among Moroccan women. Aim: To determine the prevalence of vitamin D deficiency and investigate its association with body mass index (BMI), waist circumference, and serum concentrations of parathyroid hormone, calcium, and phosphorus in a sample of Moroccan adult women. Methods: This is a cross-sectional study conducted at Mohammed V Military Hospital of Instruction, Rabat. Anthropometric measurements and biochemical analyses were performed using standard procedures Results: A total of 714 women aged 18-65 years participated in this study. The overall prevalence of vitamin D deficiency was 74.4%. Approximately 24% and 51% of women had severe and moderate vitamin D deficiency, respectively. Serum 25-hydroxyvitamin D (25(OH)D) concentrations were inversely correlated with BMI in vitamin D-deficient subjects (P = 0.036) and with parathyroid hormone 1-84 (PTH1-84) levels in the study sample (P = 0.010). PTH1-84 concentrations were greater among overweight/obese individuals compared to their non-overweight peers (P = 0.001) and tended to be higher among vitamin D-deficient women than vitamin D-sufficient women (P = 0.053). Conclusion: This study showed a very high prevalence of vitamin D deficiency in this sample of Moroccan women. Lower serum 25(OH)D levels were associated with increased BMI in vitamin D-deficient women and with elevated PTH1-84 levels among the study sample. Although these findings come from a convenience sample of women that attended a nutrition clinic, they underscore the urgent need to develop public health interventions to improve women's vitamin D status.

Qualitative Review of National Nutrition Surveillance Systems in the Eastern Mediterranean Region.

The World Food Conference in 1974 emphasized the significance of establishing global nutrition surveillance to monitor and address nutritional challenges effectively. However, many countries, especially in the EMRO region, continue to encounter substantial difficulties in regularly generating disaggregated data on nutrition. The current study aimed to review the existing nutrition surveillance systems in the region and to identify their strengths and weaknesses, as well as the challenges they face in functioning optimally. METHODS: This study focused on the functional nutrition surveillance systems in eight Arab countries; namely Kuwait, Morocco, Oman, Palestine, Saudi Arabia, Sudan, Syria, and Yemen. The study's analysis involved utilizing primary data collected from both published and unpublished reports. Additionally, a structured checklist was employed to gather information from all countries involved in the study. Furthermore, interviews were conducted with the EMRO offices to gain deeper insights into the challenges, if any, that these nutrition surveillance systems face in functioning optimally. RESULTS: All countries use health facilities as a basic source of data for their nutrition surveillance, some countries triangulate their nutrition surveillance reports with data from other sources of information such as community or school surveys. Identified nutrition surveillance approaches are closely split between those who operate in stable settings and use routine health information systems (Morocco, Saudi Arabia, Oman, and Kuwait) and other countries that operate in fragile settings; for example, Yemen, Syria, Palestine, and Sudan struggle to provide early warning reports for rapid nutritional responses. CONCLUSIONS: Nutrition surveillance systems that utilize existing health information systems are the most sustained in the EMRO region. However, by integrating data from multiple sources, such as health facilities, surveys, and population censuses, countries can provide a holistic view of the nutritional situation, enhance their response to any emergency, and can leverage the infrastructure and resources already in place for health data collection and reporting. Collaboration between countries in the region through sharing experiences and success stories is important in order to reach a standardized system that can be implemented in different settings.

Prevalence of iodine deficiency among Moroccan women of reproductive age.

BACKGROUND: Iodine deficiency disorders (IDD) affects nearly 1.9 million people worldwide. Iodine deficiency (ID) remains a public health concern not only for pregnant women, but for women of reproductive age (WRA) as well. This study was planned to evaluate the iodine status and the prevalence of iodine deficiency in a nationally representative sample of Moroccan WRA according to their socio-economic data and living areas. METHODS: This study is a cross-sectional national survey conducted on 1652 WRA aged between 18 and 49 years. Iodine status was assessed by the evaluation of the urinary iodine concentration (UIC) on spot urinary samples, using the Sandell-Kolthoff reaction, and by the estimation of iodine-rich food consumption, using a food frequency questionnaire. The World Health Organization cutoff of a median UIC of < 100 µg/l was used to define ID in the population. RESULTS: The median UIC [20th- 80th] was 71.3 µg/l [37.5-123.1] and 71% of participants had UIC < 100 µg/L, indicating insufficient iodine status and mild iodine deficiency. WRA from urban and rural areas showed an UIC median of 75.94 µg/l [41.16-129.97] and 63.40 µg/l [33.81-111.68], respectively. Furthermore, ID prevalence was significantly higher in rural areas (75.6%) as compared to urban areas (67.9%) (p < 0.05). Food frequency questionnaires analyses highlighted that dairy products are the most commonly consumed iodine-rich food, reported to be consumed daily by 43.1% of WRA. Of particular interest, 83.5% of WRA reported a weekly consumption of fish. CONCLUSION: ID is still a public health problem in Morocco highlighting the necessity to implement effective national program, including efficient salt iodization, effective nutritional education and awareness, to control iodine deficiency and prevent IDD development.

Comparison of appropriateness of Nutri-Score and other front-of-pack nutrition labels across a group of Moroccan consumers: awareness, understanding and food choices.

BACKGROUND: The front of pack nutrition label Nutri-Score, intended to help consumers orient their choices towards foods that are more favorable to health, was developed in France and applied in several European countries. Consideration is underway for its use in Morocco. This study aims to assess Moroccan consumers' perception and objective understanding of Nutri-Score and 4 other nutritional information labels (Health Star Rating, Health warning, Reference Intakes and Multiple Trafic Light) and their impact on purchase intentions. METHODS: 814 participants were asked to choose among 3 food classes (yoghurts, biscuits and cold cuts), which ones they would prefer to buy among three products with different nutritional profiles and then to rank them according to their nutritional quality. Participants first performed these tasks without a visible nutritional label, and then, after being randomized to one of five labels tested, with the nutritional label visible on front of packs. Next, the full set of tested labels was presented to the participants who were asked a series of questions regarding their preferences, the attractiveness of the labels, their perceptions, intention to use and the trustworthiness placed in the labels. RESULTS: Compared to the Reference Intake, the Nutri-Score (OR = 2.48 [1.53-4.05], p < 0.0001), was associated with the highest improvement in the ability to correctly classify foods based on their nutritional quality. The percentage of participants who improved their food choice was higher than those who worsened it for all the labels. For yogurts and cookies, the most significant improvements were observed for the Nutri-Score and the Reference Intakes: Concerning the perception of labels, the Nutri-Score is the label that received the highest number of positive responses, whether concerning the ease of being spotted (82.2%), of being understood (74%), and to provide rapid information (68.8%). The Nutri-Score was ranked as the preferred label by 64.9% of the participants. CONCLUSION: The Nutri-Score appears to be the most effective nutritional information system to inform consumers about the nutritional quality of foods in Morocco, where it could constitute a useful tool to help consumers in their food choices in situations of purchase.

Meta-Analysis and Systematic Review of Micro- and Macro-Nutrient Intakes and Trajectories of Macro-Nutrient Supply in the Eastern Mediterranean Region.

The Eastern Mediterranean Region (EMR) is experiencing a nutrition transition, characterized by the emergence of overnutrition and micro-nutrient deficiencies. No previous study has comparatively examined nutrient intake in adults across countries in the EMR. This review examined the adequacy of nutrients in adults living in the EMR. Moreover, it analyzed the food balance sheets (FBS) for 1961-2018 to identify the trajectory of energy supply from macro-nutrients in the EMR. A systematic search was conducted from January 2012 to September 2020. Only observational studies were retained with a random sampling design. An assessment of the methodological quality was conducted. Levels of nutrient daily intake and their adequacy compared to the daily reference intake of the Institute of Medicine were reported across the region. No studies were identified for half of the region's countries. Although nutrient energy intake was satisfactory overall, fat and carbohydrate intake were high. Intake of vitamin D, calcium, potassium, zinc, and magnesium were below that recommended. The analysis of the FBS data allowed for the identification of four linear patterns of trajectories, with countries in the EMR best fitting the 'high-energy-supply from carbohydrate' group. This systematic review warrants multi-sectorial commitment to optimize nutrient intake.

A Household-Based Survey of Iodine Nutrition in Moroccan Children Shows Iodine Sufficiency at the National Level But Risk of Deficient Intakes in Mountainous Areas.

Historically, mountainous areas of Morocco have been affected by endemic goiter and severe iodine deficiency. In 1995, Morocco legislated salt iodization to reduce iodine deficiency. There has been no national survey of iodine nutrition in school-age children for nearly 3 decades. Our aim was to assess iodine nutrition in a national sample of 6-12-year-old children in Morocco to inform the national salt iodization strategy. In this cross-sectional household-based survey, we randomly recruited healthy 6-12-year-old children from 180 clusters in four geographic zones (north and east, central, north and south) covering the 12 regions of Morocco. A questionnaire was completed, including socio-economic status and parental level of education. In addition, anthropometric measurements were taken to assess nutrition status, and a spot urine sample was collected to measure urinary iodine concentration (UIC). A total of 3118 households were surveyed, and 1043 eligible children were recruited, 56% from urban areas and 44% from rural areas. At the national level, the percentage of surveyed samples with UIC < 50 µg/L was 21.6% (19.2%; 24.2%), which exceeds the WHO suggestion of no more than 20% of samples below 50 µg/L, despite an adequate level of median urinary iodine concentration (mUIC) at 117.4 µg/L (110.2; 123.3). There were no statistically significant differences in mUIC comparing urban vs. rural areas and socio-economic status. However, the mUIC was significantly lower in the central (high-altitude non-coastal) zone (p < 0.004), where the mUIC (95% CI) was deficient at 89.2 µg/L (80.8; 102.9). There was also a significant difference in the mUIC by head of household education level (p = 0.008). The mUIC in Moroccan children >100 µg/L indicates iodine sufficiency at the national level. However, the percentage of surveyed samples with UIC < 50 µg/L above suggests that a significant proportion of children remain at risk for iodine deficiency, and it appears those at greatest risk are residing in the central (high altitude non-coastal) zone. A national level mUIC value may conceal discrepancies in iodine intake among different sub-groups, including those defined by geographic region.
