Overweight and Obesity and Associated Factors among Adolescent Students in Public Day Secondary Schools in Machakos County, Kenya

Background: Overweight and obesity have increased significantly worldwide, placing major economic problems on health systems. This study aims to determine socio-economic characteristics, dietary practices, physical activity levels, nutrition status, predictors of overweight and obesity, and their relationships among adolescents. Methods: The study adopted a cross-sectional analytical study design. 401 adolescents were randomly selected from five secondary day schools using a proportionate-to-size sampling method. Results: Based on the findings, one third (36.3%) of the adolescents were between ages 17-18, with more girls (55.9%) than boys. The number of meals consumed per day among adolescents was 3.34±1.24. Individual dietary diversity score among adolescents was 4.21±1.61. Based on Body Mass Index (BMI), the prevalence of overweight and obesity among boys was 5.2% and 1.8%, respectively, and for girls, it was 7.3% and 3.6%, respectively. Using bioelectrical impedance analysis, the prevalence rates for males were 8.8% and 4.1%, respectively, while for females the rates were 10.1% and 5.1%. Regression analysis revealed that the most significant predictors were energy intake and physical activity, with P˂0.05 based on BMI and bioelectrical impedance analysis. Conclusion: There is a significant relationship between nutritional status and energy intake, the number of meals, dietary diversity score, and physical activity. Physical activity and dietary practices were the most important predictors of overweight and obesity among adolescents. The study recommends nutrition education and public health interventions in schools’ curricula.

Prevalence of anhedonia, anxiety, and their impact on food consumption among postgraduate Qassim University students.

A prevalent symptom of many mental health issues, such as depression, is anhedonia, which is the inability to feel joy or pleasure. Tension-induced sensations, anxious thoughts, and bodily alterations are the hallmarks of anxiety. One known environmental factor that affects mental health is diet. In this implication, eating appetizing meals has been proposed to reduce unpleasant feelings like worry. This study aimed to indicate whether eating habits among postgraduate students are related to symptoms of anhedonia and/or anxiety. In a cross-sectional study, responses were collected from a total of 393 postgraduate students. Each student self-answered the General Anxiety Disorder-7, Snaith-Hamilton Pleasure Scale for Anhedonia, and the Food Consumption Questionnaire and reported the body weight. The prevalence of anhedonia was 28%, moderate anxiety and severe anxiety were 15.7 and 10.9%, respectively. In this research, results showed that sugary foods, fast food, and fried foods were positively associated with anxiety and anhedonia. However, fruits and vegetables were negatively associated with anxiety and anhedonia. Linear regression showed that fruit and drinking water consumption was significant with the number of meals/day. There was no significance between the number of meals per day and anhedonia; however, there was statistical significance with the total GAD-7 scale score regarding the number of meals/per day. Anhedonia and anxiety are associated with food consumption, especially foods rich in sugars, fast and fried, which help to increase positive feelings. Future studies should focus on understanding the relationship between food consumption and following a healthy diet and improving and reducing symptoms of anxiety and anhedonia in those who suffer from a stressful or task-filled lifestyle, such as students, especially postgraduate students. In addition, it focuses on the importance of awareness of the symptoms of anhedonia, which is classified as a depressive disease, and how to control anxiety to maintain better mental health.

8.K. Scientific session: Promoting Healthier and Sustainable Diets – Evidence from the Interdisciplinary MedDietMenus4Campus

Abstract Food service comprises the production of meals consumed outside the home, including consumers from all age groups and in different sectors. This service sector has evolved through the years, providing an increasing number of meals, which have been drifting away from the Mediterranean Food Pattern. Food service is an important setting for public health interventions, educating consumers and modulating behaviours through the meals provided. Prior research on eating habits has mainly focused on a single stakeholder - typically consumers - and on a narrow set of outcome variables. Although these studies provide important clues about the determinants of adherence to food offer, research has yet to address this issue using an integrative approach of multiple stakeholders (e.g., the consumers, food providers, and decisors) across a set of different variables. Also, intervention initiatives, usually act only on the environment without strategies that efficiently engage all the stakeholders involved. In contrast, to promote behavioral change this research will focus on Social Marketing as it has been acknowledged as an effective strategy to enhance the health and well-being of consumers. Establishing and managing long-term partnerships that include different groups of stakeholders - consumers, government, retailers, and other players - are key elements in the application of mid and upstream social marketing to complex issues. The project’s main ambition is to change the food service paradigm, by creating and implementing a new healthy and sustainable food service concept complying with the Mediterranean diet, as well as solutions that comply with consumers’ new needs, and also developing and implementing strategies that engage all the stakeholders with this concept. We expect to create the reference in terms of food offer that will be demanded by consumers of the next generations and the standpoint to inspire the other food service sectors/ settings to achieve an effective and sustainable food offer change and positively influence food service consumers’ food patterns towards Mediterranean recommendations. In this workshop, the findings of the project will be presented focusing on examining the barriers and facilitators of adherence to the Mediterranean Diet in the menus offered in public high education institutes canteens in Portugal, Turkey, and Croatia. To promote the identification of effective intervention pathways, we take on an interdisciplinary approach, integrating the theoretical and methodological frameworks of Nutrition, Psychology, and Marketing. Key messages • Provide an overview of an interdisciplinary approach to promote healthier and more sustainable food offered in university canteens. • Present the pathway to develop social marketing strategies to engage different stakeholders in effective food behaviour change.

Exploring the Relationship Between Experiences of Violence and Subjective Wellbeing: A Cross-Sectional Survey Among School Teachers in Nyarugusu Refugee Camp in Tanzania.

Experiences of violence have been reported to be associated with lower levels of subjective wellbeing (SWB). However, little is known about this association in conflict settings and among forcibly displaced populations. In this study we exploit data from a representative sample of refugee teachers from Nyarugusu Refugee Camp collected as part of a larger study, to examine the association between demographic characteristics and SWB, and between experiences of violence and SWB. Three cross-sectional surveys of primary and secondary school teachers were conducted, collecting data on lifetime experience of violence (physical and sexual) and SWB (measured by life satisfaction and current happiness, on 1-5 Likert scales). Linear mixed models were used to estimate the associations between violence and SWB accounting for teacher and school clustering, unadjusted and adjusted for main factors associated with SWB. The 3 surveys included 1,666 responses completed by 885 teachers. Country of origin and number of meals consumed per day were strongly associated with SWB. Individuals who experienced physical violence reported on average, 0.13 lower life satisfaction scores (95% CI [-0.23, -0.02], p = .016) compared to those who did not experience physical violence, while survivors of sexual violence reported on average, 0.24 lower happiness scores ([-0.43, -0.05], p = .014) compared to those who did not experience sexual violence, after adjusting for confounders and clustering. We found an important negative association between past experience of violence and SWB in a refugee camp setting. These findings contribute to the evidence that violent experiences are likely to have a long-lasting impact on people's wellbeing. There is a need for improved mental health and psychosocial support in humanitarian settings.

Adherence to Mediterranean diet in Moroccan school-age adolescents: sociodemographic, socioeconomic and lifestyle determinants

BackgroundDespite its benefits, the Mediterranean diet (MD) is abandoned or not adopted by the younger generations in most Mediterranean countries.ObjectiveThe aim here was to examine some factors determining adherence to MD in Moroccan school-age adolescents.Material and methodsA cross-sectional survey was conducted in a school setting among 386 students (148 boys and 238 girls), aged 14 to 18 years, randomly selected and from different socioeconomic strata. A structured questionnaire was used to collect sociodemographic, socioeconomic and lifestyle data. Physical activity was assessed using the short French version of the IPAQ questionnaire. The KIDMED test was used to assess adherence to the Mediterranean diet. Weight, height and waist circumference were measured according to WHO standards. Body mass index (BMI) and waist�to-height ratio (WHtR) were calculated. Statistical ANOVA test was used for to compare multiple means, Student’s t-test for independent samples, <i>Chi</i><sup>2</sup> test for categorical variables and multinomial logistic regression analysis to identify factors associated with adherence to the MD amongst adolescents sample.ResultsAdherence to the MD in this population was very low, with nearly 53% having poor adherence and only 7.7% reporting optimal adherence. Multinomial regression analyses showed that poor adherence is correlated with female gender (p=0.042), low paternal education (p=0.004), limited number of meals (p=0.006), advanced age (p=0.005) and inadequate sleep duration (p=0.027). In contrast, better adherence appears to be correlated with a high number of meals per day (p<0.001) and a better socio-professional class of the father (p<0.001).ConclusionsThis study revealed a low prevalence of good adherence to MD confirming a transition of the study adolescents towards a Westernized diet. Targeted nutritional intervention programs should be implemented to improve adherence to the MD among Moroccan adolescents, by promoting healthy eating habits.

Eating habits of students during a typical exam period-Case of Kosovo

The exam period is a stressful period for students, which often influences them to make wrong food choices. This study examines the eating habits of students during a typical exam period, to understand their food patterns or dietary choices, in a period when they have greater stress due to the high academic demands at the university. The 200 students of different academic levels at the University of Prishtina participated in this research. Data have been compiled through online questionnaires where the respondents were asked to anonymously declare their health status, the number of meals they take per day during a typical exam period, their food preferences, physical activity, and sleep. Results showed that Kosovar students have unhealthy eating habits during exam periods. They have a disorder in the time and number of meals they take during the day on a typical exam period, compared to other periods of the year. The findings of this research contribute to the existing literature related to dietary habits of students in stressful periods, providing knowledge for students and addressing the issue of education for healthy nutrition in educational institutions.

Nutritional status of khat (Catha-edulis) chewing adult males in Nakawa division, Kampala city, Uganda

Khat (Catha edulis) also known as “Mairungi” in Uganda, is a green shrub whose leaves are chewed in social gatherings and designated hotspots mainly for its euphoric effect. The socio-economic and health impacts of khat have been previously reported. However, the nutritional implications of khat chewing need to be investigated. A cross-sectional study with a descriptive approach was done to assess the nutritional status of adult male users of khat in the Nakawa division, Kampala city. Using chain sampling, khat users and hot spots were mapped, identified, and listed. Using simple random sampling, 100 khat users were targeted to consent for structured interviews and an assessment of nutritional status over a 3-month persuasion period. Anthropometric data were used to compute the Body Mass Index (BMI) and dietary information was assessed based on food groups consumed and thresholds of Recommended Dietary Allowances (RDA). The degree of relationship among variables was statistically evaluated using, chi-square analyses and the ANOVA test. Statistical significance was considered at P < 0.05. Confidentiality was observed by the use of anonymous questionnaires and coded datasheets. The majority of khat users chewed khat daily 56.0% and mixed khat chewing with other intoxicants such as alcohol 35.0%, cigarettes 15.0%, and cannabis 12.0%. The main driver towards khat chewing in Nakawa was peer pressure 60.0%. The Dietary Diversity Score (DDS) was low, medium and high among 20.0%, 57.0% and 23.0% of khat users, respectively. The DDS was significantly associated with the hours spent on khat chewing X2(4) 10.156, P = 0.025 with most users spending more than four hours, and the frequency of khat chewing X2(4)14.423, P = 0.038. Of the 100 respondents, 26.0% were underweight and 3.0% were overweight. The BMI was significantly associated with age P = 0.029, marital status P = 0.023, frequency of khat chewing P = 0.038, the number of meals P = 0.013 and the dietary diversity scores P < 0.001 in khat users. Khat chewing and its associated habits predispose khat users to a double jeopardy of malnutrition and non-communicable diseases (NCDs). There should be tighter control of khat use through policy and legislation with community-based measures to regulate its demand and supply. Key words: Khat Chewing, Mairungi, Nutritional Status, Body Mass Index, Nakawa, Uganda

Diet as a challenge and a strategy: on the phenomenon of diet rationalisation in everyday life

This article describes the diet catering service (delivering ready-made meals to customers’ homes or work in a selected period) as an example of rationalization and professionalization of diet. The article is based on the results of interviews conducted with 15 users of dietetic catering from Poland, conducted between 2021 and 2023. The aim of the interviews was to try to answer the question of what benefits the respondents derived from using dietetic catering in their everyday life. As the results of the analysis show, respondents try to live a healthy lifestyle, which they do not always succeed in doing. Outsourcing the preparation of meals to the specialized companies allows them to save time and receive well-balanced meals, at selected times of the day adapted to their rhythm of work. There is a compromise between meeting healthy eating norms and social norms relating to food consumption, both in terms of mealtimes, the number of meals per day as well as what is meant by a ‘proper lunch’.

Associations of clinical and modifiable behavioral risk factors with the histological progression of squamous intraepithelial lesions.

Cervical cancer is the third most common cancer in women worldwide. Human papillomavirus (HPV) has been established as a cause of invasive cervical cancer. However, HPV is predominantly transient and only a minority of cases persist and progress clinically. Certain epidemiological factors have been suggested to increase the risk of HPV persistence and progression. In the present study, 893 women were investigated, with an age range from 25 to 60 years old. PAP smears and colposcopy were used for assessment. Of these women, 108 were diagnosed with squamous intraepithelial lesions (SILs) and were further divided into high-grade SIL (HSIL) and low-grade SIL (LSIL). The dietary habits, sleep patterns and gynecological histories of these participants were studied, and it was found that the probability of having <3 meals a day [odds ratio (OR), 4.35; 95% confidence interval (CI), 1.73-10.95], having an unbalanced diet (OR, 3.90; 95% CI, 1.44-10.55), breakfast skipping (OR, 6.32; 95% CI, 2.40-16.61) and disrupted sleep (OR, 4.42; 95% CI, 1.79-10.93) was significantly higher in the HSIL group compared with the probability in the LSIL group. In addition, participants who had pregnancies prior to the age of 20 were 2.85 times more likely to have more advanced disease (OR, 2.85; 95% CI, 1.22-6.71). Cervical erosion was higher in the HSIL group compared with that in the LSIL group (OR, 3.31; 95% CI, 1.36-6.96). The present study highlights the protective effects of meal numbers, nutritious diet and sleep hygiene against HPV and the progression of SIL.

The impact of eating alone on food intake and everyday eating routines: A cross-sectional study of community-living 70- to 75-year-olds in Sweden

BackgroundEating is fundamental not only to survival and health, but also to how humans organise their social lives. Eating together with others is often seen as the healthy ideal, while eating alone is highlighted as a risk factor for negative health outcomes, especially among older adults. This paper, therefore, investigates the relationship between the frequency and subjective experience of eating alone and food-related outcomes among 70- to 75-year-olds in Sweden.MethodsA survey was distributed to a nationally representative random sample of 1500 community-living in Sweden, aged 70–75 years. Two different constructs of eating alone (objective and subjective) were measured, along with the following food-related outcomes: a food index, intake of food groups, consumption of ready-made meals, number of main meals per day, and body mass index (BMI).ResultsIn total, 695 respondents were included in the final sample. A quarter of the respondents were categorised as eating alone, of which a small proportion reported that doing so bothered them. There were no associations between eating alone and food index scores, BMI, or intake frequencies of fruits and berries, or fish and shellfish. However, people eating alone were less likely to report eating three meals per day (OR: 0.53, CI: 0.37–0.76, p = 0.006), less likely to report higher intake frequencies of vegetables and snacks, sugary foods, and sweet drinks (adjusted OR: 0.68, CI: 0.48–0.95, p = 0.023 resp. OR: 0.59, CI: 0.43–0.81, p = 0.001), and more likely to report higher intake frequencies of ready-made meals (adjusted OR: 3.71, CI: 2.02–6.84, p < 0.001) compared to those eating together with others. The subjective experience of eating alone did not have an impact on food-related outcomes.ConclusionEating alone or with others played a role in participants’ food intake, and seemed to influence aspects of the organisation of everyday eating routines rather than overall dietary healthiness or weight status. Our findings add to the previous body of research on commensality, eating alone, and health among the older population, providing insights into the development of future health policies and research.

Exploring the associations between chronotype, meal frequency, and physical activity: A population-based study in adults

ABSTRACT Chronotype is an established concept designed to capture the internal clock’s phase in real-life conditions. It is vital in many aspects of daily life and can interfere considerably with numerous factors in a given population. Recognizing nonmodifiable and modifiable factors is crucial for identifying covariates of interest when studying the link between chronotype and health status. To date, chronotype and its related factors have not been extensively investigated. The present study aimed to explore the association of chronotypes with meal frequency, physical activity, and demographic factors among the Saudi population. This cross-sectional web-based questionnaire involved 1369 adults (aged 18 years and above) from the general public in Saudi Arabia and was conducted between March and May 2019. Chronotype was assessed using the reduced version of the original Horne and Ostberg morningness-eveningness questionnaire (MEQ). Meal frequencies and demographics data (age, gender, marital status, place of residence, educational level, employment status, income) were obtained. Physical activity level was also obtained using the international physical activity questionnaire. The MEQ scores group individuals into three categories: morning-type, neither-type, and evening-type. The neither-type individuals represented 41.6% (95% confidence interval [CI], 37.5% − 45.6%) of the study population, followed by the morning-type (34.1%; 95% [CI], 29.8% − 38.4%), then the evening-type (24.3%, 95% [CI], 19.6% − 28.9%). Chronotype was significantly associated with age, marital status, employment status and monthly income (All p < 0.05). Significant associations between chronotype with meal frequencies (number of meals per day, breakfast frequency, lunch frequency, and dinner frequency) and physical activity were also observed (All p < 0.05). This study highlights that meal frequencies and physical activity levels are associated with chronotype distribution. Furthermore, demographics, including age, marital status, employment status, and income, were associated with chronotype distribution.

Manipulation of feeding patterns in high fat diet fed rats improves microbiota composition dynamics, inflammation and gut-brain signaling

Chronic consumption of high fat (HF) diets has been shown to increase meal size and meal frequency in rodents, resulting in overeating. Reducing meal frequency and establishing periods of fasting, independently of caloric intake, may improve obesity-associated metabolic disorders. Additionally, diet-driven changes in microbiota composition have been shown to play a critical role in the development and maintenance of metabolic disorders. In this study, we used a pair-feeding paradigm to reduce meal frequency and snacking episodes while maintaining overall intake and body weight in HF fed rats. We hypothesized that manipulation of feeding patterns would improve microbiota composition and metabolic outcomes. Male Wistar rats were placed in three groups consuming either a HF, low fat diet (LF, matched for sugar), or pair-fed HF diet for 7 weeks (n = 11–12/group). Pair-fed animals received the same amount of food consumed by the HF fed group once daily before dark onset (HF-PF). Rats underwent oral glucose tolerance and gut peptide cholecystokinin sensitivity tests. Bacterial DNA was extracted from the feces collected during both dark and light cycles and sequenced via Illumina MiSeq sequencing of the 16S V4 region. Our pair-feeding paradigm reduced meal numbers, especially small meals in the inactive phase, without changing total caloric intake. This shift in feeding patterns reduced relative abundances of obesity-associated bacteria and maintained circadian fluctuations in microbial abundances. These changes were associated with improved gastrointestinal (GI) function, reduced inflammation, and improved glucose tolerance and gut to brain signaling. We concluded from these data that targeting snacking may help improve metabolic outcomes, independently of energy content of the diet and hyperphagia.

Socio-spatial networks and capital in small rural primary school voluntary activity

ABSTRACT Small primary schools and schools with the lowest number of free school meal (FSM) eligibility are increasingly reliant on voluntary activity for the provision of core services. Significant disparities in where and how this voluntary activity happens risk widening inequalities between schools, especially when policies directly encourage them (and funding cuts necessitate them) to turn to their communities for support. However, we do not know how these differences play out in practice or what the implications might be. Drawing on ethnographic research, this paper explores how voluntary activity undertaken in small rural primaries is facilitated through socio-spatial networks (interpersonal connections rooted in space) and how capital is mobilised (and converted) through these networks. This research revealed how the work of education is carried out through many socio-economic modes, by different people and across a range of spaces, and that this influences the education provided in these environments.

Life history data of four populations of Triatoma mexicana (Hemiptera: Reduviidae) from Central Mexico.

Triatomine bugs are vectors for the Trypanosoma cruzi Chagas parasites, the etiological agent for Chagas disease. This study evaluated 6 epidemiologically significant behaviors (development time, number of blood meals required for molting to the next instar, mortality rate, aggressiveness, feeding duration, and defecation delay) across 4 populations of Triatoma mexicana Herrich-Schaeffer (Heteroptera: Reduviidae), a major T. cruzi vector in Central Mexico. We collected triatomines from areas characterized by high (HP), medium (MP), medium-high (MHP), and low (LP) prevalence of human T. cruzi infection. The MHP population had the shortest development time, <290 days. Both the HP and MP populations required the most blood meals to molt to the next instar, with a median of 13. Mortality rates varied across all populations, ranging from 44% to 52%. All of the tested populations showed aggressive behavior during feeding. All populations shared similar feeding durations, with most exceeding 13 min and increasing with each instar. Quick defecation, during feeding, immediately after or less than 1 min after feeding, was observed in most nymphs (78%-90%) from the MP and MHP populations and adults (74%-92%) from HP, MP, and MHP populations. Though most parameters suggest a low potential for T. mexicana to transmit T. cruzi, unique feeding and defecation behaviors in 3 populations (excluding the LP group) could elevate their epidemiological importance. These population-specific differences may contribute to the varying prevalence rates of T. cruzi infection in areas where T. mexicana is found.

Genetic parameters of feeding behaviour traits in ducks bred for foie gras production

The mule duck accounts for over 90% of French foie gras production, a sector where feed represents two-thirds of production costs. This study focuses on analysing the feeding behaviours of the mule duck and its parental populations (Pekin and Muscovy) using automated feeders. To assess feed efficiency, feed conversion ratio and residual feed intake were analysed, along with six traits derived at the daily and meal levels. Genetic parameters were estimated separately in purebred populations, as well as with a joint crossbred model that estimated the parental contributions to the hybrid crossbred performances. In relation to higher feed intakes and much−reduced feeding times (P < 0.001), the feeding rate in the Pekin population was twice as high as in the Muscovy population (19 g/min vs 9 g/min), while the mule duck exhibited a large heterosis for this trait (29 g/min). Feeding traits exhibited moderate (0.38 ± 0.11) to high (0.65 ± 0.11) heritabilities. Similar correlation patterns were observed between feeding traits in the two parental populations. In the Pekin line, the feed conversion ratio did not significantly correlate with feeding traits except for daily feed intake. However, in the Muscovy population, it was negatively correlated with the number of meals (−0.51 ± 0.21) and positively with meal feed intake and meal duration (+0.79 ± 0.17 and + 0.71 ± 0.26, respectively). The contributions of the two parental species to the hybrid’s performance differed, with the Pekin contributing more to feeding and meat traits compared to the Muscovy. They were similar only for liver weight. Additionally, unfavourable correlations between meat traits and liver traits were estimated in both pathways. Genetic relationships between feeding traits and slaughter traits varied by parental origin, suggesting different strategies for improving hybrid performance in the two parental species. However, in both pathways, genetic correlations between feed conversion ratio and meat traits (breast muscle and thigh weights) were favourable (<−0.42 ± 0.18), whereas they were unfavourable (>0.41 ± 0.20) for fatty liver weight. Altogether, improving liver traits and feed efficiency in the hybrid through selection in the parental populations could be enhanced by considering feeding traits recorded with electronic feeders, provided that adverse correlations are properly accounted for in a multitrait index.

Ecological study of the reach of congregate vs. grab-and-go summer meals in New York City

Participation in school meals is associated with many benefits. However, participation in school meals served in the summer through the Summer Food Service Program (SFSP) is low due to many barriers, including program requirements such as congregate feeding. During COVID-19, these requirements were waived, allowing grab-and-go meals. The purpose of this study is to compare the number of SFSP breakfast and lunch meals served during the summers of grab-and-go meals (2020 and 2021) to prior summers of congregate feeding (2014–2019) in New York City (NYC). This study is an ecological study of NYC public school geographic districts (n = 32). The primary outcome is the total number of SFSP meals served per student. Using the repeated-measures ANOVA, the results show a significant increase in the number of SFSP meals served per student during the first summer (2020) of grab-and-go meals compared to summers 2016–2019 (p ≤ 0.01) but no significant differences during the second summer (2021) of grab-and-go meals compared to summers 2014–2019. However, there was a significant increase in the number of breakfast meals served in August per student during both the first and second summer of grab-and-go meals compared to summers 2014–2019 (p < 0.05). Among NYC public schools, the waivers may increase the reach of breakfast meals served in August, when there are fewer summer school activities. While there is a need for more research, policymakers may consider making waivers that allow grab-and-go meals permanent flexibilities for the SFSP to increase access to summer meals.

Clinical characteristics and caries risk assessment of tobacco heating systems smokers, cigarette smokers and non-smokers: a cross-sectional study.

The study compared clinical characteristics and caries risk assessments between tobacco heating system (THS) smokers, cigarette smokers and non-smokers. General data, data regarding fluoridation, smoking and dietary habits was obtained through a questionnaire. Caries experience was assessed by the DMFT index; the amount of biofilm by the Full mouth plaque score index; the amount of salivation by the quantum of stimulated salivation test; salivary pH with pH indicator strips and salivary number of S.mutans and Lactobacilli by cultivation on agar plates. The Cariogram method was used to assess caries risk. No differences between the groups was detected regarding education level, average daily number of meals, fluoridation programs, systemic diseases, and caries experience. The groups significantly differed in the amount of salivary S.mutans and Lactobacilli (p < 0.001), accumulated biofilm (p = 0.034), salivation quantum (p < 0.001), and saliva pH (p = 0.009). Exposure to tobacco smoke and heated tobacco aerosol increased the accumulation of biofilm and decreased salivary pH. Smoking increased S. mutans, while THS consumption decreased salivation and Lactobacilli the most. The Cariogram analysis found no differences in chances of avoiding new caries lesions between the groups, but a significant difference in developing caries lesions due to dietary habits was detected (p < 0.001) with non-smokers having higher risk than smokers, but not than THS consumers. THS and cigarette smoking were related to clinical characteristics that affect caries activity even though the caries risk assessment revealed no significant difference in the chances of avoiding new caries lesions between the groups. THS and cigarette smokers could have higher caries activity than non-smokers. The clinical study protocol has been registered on ClinicalTrials.gov under the ID number: NCT06314100.

Food consumption patterns, seasonal dietary diversity, and factors affecting food intake in rural Eastern Uganda: A mixed-methods cross-sectional study

This mixed-methods cross-sectional study examines food consumption patterns, dietary diversity, and factors affecting food intake and malnutrition in the rural Mbale District in Eastern Uganda, during both wet and dry seasons. Participants (n = 100; 66% females) completed a food frequency questionnaire identifying foods and beverages consumed in the preceding 12 months. Individual interviews (n = 8) were conducted with key workers. Analysis of seventeen food items revealed seasonal variations in carbohydrate and protein sources. During the dry season, staples like matooke (mashed boiled plantains) and sweet and Irish potatoes were affected, while protein-rich foods such as beans and groundnuts saw increased consumption in the wet season. Fruit and vegetable intake also rose during the wet season. The main causes of malnutrition that emerged from the interviews were the lack of knowledge about food and nutrition, financial struggles, climate impact, and cultural beliefs. The last theme covered strategies to combat malnutrition. Although carbohydrate intake remains consistent throughout seasons due to reliance on posho (maize flour porridge) and cassava, variations in the number of meals and protein sources, particularly beans and groundnuts, were observed. Both of these, being the primary protein sources in rural households' diets, are highly susceptible to climate fluctuations. This may pose significant implications for food security, as heightened climate instability may impede their production. Solutions to combat malnutrition discussed by the interviewees include education, employment, family planning, and healthcare improvements. Professionals emphasise the need for comprehensive approaches to address these complex issues. In addition, data on food consumption during the dry and wet seasons should be collected as a difference in food consumption during the seasons may become more prominent with the need to implement tailored interventions.

A Critical Review on the Bioavailability Promotion of the Food Bioactive Compounds: Nano Lipid Carriers Perspective

Currently, a large number of people favor meals that are rich in nutraceuticals and phytochemical compounds, which help with the treatment or prevention of chronic diseases. Oral bioavailability is a crucial component of phytochemical bioefficiency, and endogenous mechanisms have a significant impact on how well nutraceuticals and phytochemicals are absorbed by the body. In addition to endogenous variables, exogenous factors that impact the bioavailability of bioactives include the food matrix, food processing, and food storage. Different delivery systems have evolved in this regard, and nanoscale delivery tools have also been created. Delivery methods that use nanostructured lipid carriers show benefits such as enhanced loading capacity, solubility, encapsulation effectiveness, storage stability, bioavailability, and half-life. They also provide safe food systems and regulated release. In this review, the outcomes of recent experimental reports are comprehensively reviewed. In addition, the food processing, storage, gut milieu circumstances, the release process from the food and nano delivery systems in the gastrointestinal tract (GIT) milieu, interactions with other GIT constituents, main delivery systems based on nanostructured lipid carriers for their encapsulation and eventually encapsulating technological barriers, food safety concerns, and regulatory issues of nutraceutical and phytochemical compounds are discussed.
