Dietary intake and food behaviours of Senegalese adolescent girls.

BACKGROUND: Malnutrition is a public health concern in low- and middle-income countries. In Senegal, 35% of adolescent girls are undernourished and 56% are anemic. METHODS: This study assessed the dietary intake of 14-18-year-old adolescent girls in Dakar, Senegal. Specifically, the study 1) assessed their intake in energy, fibre, macro- and micronutrients, 2) described the types and the quality of the foods they consume, and 3) assessed some of their eating behaviours. Dietary intake was measured using three non-consecutive 24-h recalls from 136 adolescent girls attending two colleges. Energy and nutrient intakes were measured and compared to recommendations. Foods were classified by food group and by whether they were healthy or unhealthy. Adolescents' daily intake (g) of fruits and vegetables, as well as the proportion of girls who ate breakfast and who consumed three meals a day were calculated. RESULTS: Sodium intake was high, while fibre intake was low. On average, 40% of the adolescents' total energy intake came from fats. Mean intakes of zinc and calcium were higher on the weekend than on weekdays, while the opposite was observed for sodium. Eighty-three percent of adolescents had an inadequate intake of iron and 99% were at risk of calcium deficiency. Approximately 60% of the foods consumed were classified as healthy, however, the majority came from grains. CONCLUSIONS: Adolescent nutrition deserves attention given the poor quality of their dietary intake which may put them at risk of malnutrition and chronic diseases. These findings may be used to help improve programs targeting Senegalese adolescent girls' nutrition.

Feeding practices and factors associated with the provision of iron-rich foods to children aged 6-23 months in Matam area, Senegal.

OBJECTIVE: The objectives of this study were to document feeding practices amongst rural Senegalese children aged 6 to 23 months and to investigate psychosocial and environmental factors associated with the provision of iron-rich foods (IRF). DESIGN: This was a cross-sectional study conducted from January to July 2018. SETTING: The study took place in the region of Matam, northern Senegal. PARTICIPANTS: Ninety-eight mothers of children aged 6-23 months. RESULTS: Results show that 27·6 % of children were fed according to the minimum acceptable diet, and 55·1 % and 53·1 % had the minimum diet diversity and minimum meal frequency, respectively. About 65·3 % of mothers provided IRF to young children the day before the survey, mostly fish. Mother's intention to provide IRF to their children was not associated with the provision of these foods neither was the perceived behavioural control. Child's age (OR = 1·14, 95 % CI (1·03, 1·26), P = 0·012) and household food insecurity score (OR = 0·80, 95 % CI (0·68, 0·96), P = 0·014) were the predictors of the provision of IRF to children aged 6-23 months. CONCLUSIONS: Household food insecurity status and age of the child rather than mothers' psychosocial factors were significant predictors of IRF consumption amongst children aged 6-23 months in the study area. More attention should be given to food environment and child-related factors in order to improve children feeding practices and, in particular, their consumption of IRF in the study setting. For instance, home visits and the 5-month-old vaccine consultation in health centres might be opportunities to reinforce the importance of providing IRF as part of complementary foods from the age of 6 months. Implementation of measures for the improvement of socio-economic conditions and food security of households would also be valuable.

Assessing the Food Availability and Food Insecurity Situation among Communities of Matam Region, Senegal.

Matam is one of the poorest and most food-insecure regions of Senegal. In the past years, repeated environmental shocks such as drought have limited the access to food and it is unclear whether food insecurity is more a function of food availability (FA) and accessibility at the community level (CL) or more related to FA at the household level (HL). To better understand the FA and food security (FS) situation in this region, in 2018, a cross-sectional study was conducted in 103 households living in four villages. Through focus group discussions and direct observations, data on food available at HL and CL were collected as well as on food affordability and household FS. Overall, between 49 and 64 different foods, mostly from plant source, were identified. Around 75% of households had 0 to 3 foods and 7%, 7 to 10; 64% of all households were severely food insecure. FA at HL and its socioeconomic status were positively associated with household FS whereas FA at the CL was negatively associated. Although food assistance may be required to respond to shocks in the area, investments could be made to improve households` socioeconomic level to enhance their access to food.

Psychosocial factors and intention to use the nutrition care process among dietitians and dietetic interns.

PURPOSE: The theory of planned behaviour was used to explore the factors (i.e., attitude, subjective norm, and perceived behavioural control) affecting the intention of dietetic internship educators, new dietetic graduates, and dietetic interns to use the nutrition care process (NCP) in their clinical practice. METHODS: Participants (n=55) were recruited from the Bachelor of Science in Nutrition program at Université Laval. They completed an online quantitative questionnaire assessing their intention to use the NCP in their clinical practice, as well as associated psychosocial factors. Open-ended questions were also used to gain a further understanding of the salient beliefs underlying participants' intention to use the NCP. RESULTS: Intention to use the NCP in practice and associated psychosocial factors were similar and favourable within the three participant groups. Subjective norm and perceived behavioural control were the psychosocial factors that significantly predicted an intention to use the NCP. The most cited perceived barrier to use of the NCP was a lack of knowledge, while the most cited facilitator was training opportunities. CONCLUSIONS: Our results indicate that successful implementation of the NCP will likely require the development of theoretical and practical training activities for both pre-licensure students and experienced dietitians.

[Not Available]. / Influence du jeûne du Ramadan sur les sensations d'appétit chez des musulmans diabétiques de type 2 au Mali.

The objective of this study was to examine the influence of Ramadan fast on appetite sensations, nutritional intakes and body weight in Malians with type 2 diabetes. Appetite sensations were assessed before Ramadan and then at the second, ninth, and sixteenth days of Ramadan (period). A total of 24 subjects recorded their appetite sensations every 2 h between 0800 and 2200 h using visual analogue scales. Daily energy intakes were estimated by a 48-h food recall (before and during Ramadan). Results showed a significant sex effect for desire to eat (p < 0.04) and a significant period effect for desire to eat and fullness (p < 0.01). Significant sex by period interactions were observed for fullness (p < 0.001), desire to eat (p < 0.01), and prospective food consumption (p < 0.03). Moreover, significant sex by period by time interactions were found for all appetite sensations (p < 0.007). Interaction effects were mainly explained by sex differences in appetite sensations before rather than during Ramadan. Although a significant body weight loss was observed in men and a significant decrease in waist circumference was found in women (p < 0.05), no significant changes in reported average daily energy intakes were observed in either men or women. According to these preliminary results, Ramadan fasting has an impact on appetite sensations that is probably not the same in men and women.

Nutritional strategies to prevent hypoglycemia at exercise in diabetic adolescents.

UNLABELLED: Studies on nutritional strategies to prevent exercise-induced hypoglycemia in adolescents with type 1 diabetes are scarce. OBJECTIVE: This study aimed to compare the effect of two food strategies on blood glucose (BG) during and after 60 min of moderate-intensity exercise. METHODS: Subjects performed exercise 120 min after breakfast in three conditions: 1) standardized breakfast + preexercise placebo beverage (PL), 2) standardized breakfast + preexercise CHO beverage (8 mg of CHO·kg of body weight·min of exercise; CHO), or 3) protein-supplemented breakfast (8 mg of protein·kg of body weight·min of exercise added to the standardized breakfast) + preexercise placebo beverage (PROT). As soon as BG falls <4 mmol·L or symptomatic hypoglycemia occurred during exercise, the session was stopped and CHO tablets were provided to correct hypoglycemia. RESULTS: Ten subjects (age = 14.0 ± 1.5 yr) participated in all conditions. BG decreased by 6.0 ± 1.9, 1.0 ± 3.1, and 4.6 ± 1.9 mmol·L in PL, CHO, and PROT conditions, respectively (P < 0.05). The proportion of subjects reaching hypoglycemic values or sensations of hypoglycemia was significantly different between conditions with 4/10, 1/10, and 0/10 in the PL, CHO, and PROT conditions (P < 0.05). CONCLUSIONS: The preexercise CHO beverage induced the least dramatic BG decrease during exercise. The PROT breakfast induced an overall similar BG drop compared to PL, a larger BG drop compared to CHO, but a similar rate of hypoglycemia compared to CHO. Our results suggest that taking CHO supplement before unplanned exercise is still the best strategy to prevent exercise-induced hypoglycemia in an adolescent population. However, a protein supplement strategy may also have some benefits in limiting the rate of hypoglycemia during and immediately after exercise.

Lack of effect of dietary conjugated linoleic acids naturally incorporated into butter on the lipid profile and body composition of overweight and obese men.

BACKGROUND: Dietary conjugated linoleic acid (CLA) is known to reduce atherosclerosis, plasma total and LDL-cholesterol concentrations, and body fat accumulation in several animal species. Of the few studies that investigated the effects of CLA supplementation in humans, all used commercially formulated oral supplements made from a mixture of CLA isomers. OBJECTIVE: We compared the effects on plasma lipoproteins and body composition of the consumption of a modified butter naturally enriched with CLA (CLA-B: 4.22 g CLA/100 g butter fat) by the addition of sunflower oil to the diet of dairy cows with the consumption of a control butter (CON-B) that was low in CLA (0.38 g CLA/100 g butter fat). DESIGN: In a crossover design study including an 8-wk washout period, 16 men [x +/- SD age: 36.6 +/- 12.4 y; body mass index (in kg/m2): 31.2 +/- 4.4] were fed each of the 2 experimental isoenergetic diets, providing 15% of energy as protein, 45% as carbohydrates, and 40% as lipids, of which >60% was derived from experimental fats, for 4 wk. RESULTS: Consumption of the CLA-B diet induced a significantly (P < 0.05) smaller reduction in plasma total cholesterol and in the ratio of total to HDL cholesterol (-0.02 mmol/L and -0.00, respectively) than did consumption of the CON-B diet (-0.26 mmol/L and-0.34, respectively). Abdominal adipose tissue area measured by computed tomography showed no difference in accumulation of either visceral or subcutaneous adipose tissue after the 2 experimental diets. CONCLUSION: These results suggest that a 10-fold CLA enrichment of butter fat does not induce beneficial metabolic effects in overweight or obese men.

Seasonal vitamin D intake in Quebec preschoolers.

As a number of seasonal factors affect cutaneous synthesis of vitamin D, especially in young children, our objective was to verify if winter and summer vitamin D intakes in Quebec preschoolers reach the adequate intake of 5 microg/day. A three-month retrospective food frequency questionnaire and a 24-hour food recall were used with parents of 98 children (mean age 56 months) in summer and of 72 of these children (mean age 65 months) in winter. To ensure completeness of data, vitamin D content of foods not covered in the Canadian Nutrient File was taken from other sources. According to the food frequency questionnaire, total vitamin D intakes were 9.7 +/- 4.3 microg/day in summer and 11.6 +/- 4.8 microg/day in winter. Only 10% of children in summer and 7% in winter had an intake below 5 microg/day. The 24-hour food recall vitamin D intake estimate was lower (summer 7.0 +/- 3.8 microg/day, winter 7.2 +/- 4.2 microg/day). This difference could be partly due to a discrepancy in the estimation of multivitamin supplement intake. However, according to both estimates, vitamin D intakes appeared generally adequate in this sample of Quebec preschoolers.
