Assessing sugar intake rapidly - a short form of the Marburg Sugar Index (MSI)

BACKGROUND

Sugar intake is a major nutritional factor in the development of dental caries. To further clarify its contribution to oral health-related diseases, population-based investigations are recommended. To facilitate economic and reliable assessment of sugar intake, a short form of the approved Marburg Sugar Index (MSI) was developed.

METHODS

According to the principles of item reduction based on original data, a six-item-short form was constructed. A total of 468 participants (aged 15-81) answered the short form together with the long form in a counterbalanced cross-over design, and with two questionnaires concerning self-efficacy and decisional balance in oral health to verify construct validity.

RESULTS

Comparable item characteristics to the original MSI and a high correlation with the long form prove the usefulness of the short form, which was processed by the participants in less than one minute. Low correlations to the other two constructs show discriminant validity.

CONCLUSION

The new short form of the MSI (MSI-S) can replace the long form, especially in population-based studies with no restrictions on assessment quality but with sufficient time saved to add other variables necessary to explore oral health-related issues.

Health and Sustainable Nutritional Choices from Childhood: Dietary Pattern and Social Models

BACKGROUND

The role of diet in the pediatric age for optimal development, achievement, and maintenance of a healthy status is well recognized. Increasing attention is nowadays also paid to reducing the burden of human nutrition on the planet's health for present and future generations.

SUMMARY

Beyond environmental sustainability, the transition to diets rich in animal and processed foods contributes to an overall unhealthy nutritional status leading to an increased prevalence of obesity- and diet-related noncommunicable diseases. Childhood overweight and obesity are a growing public health crisis worldwide. The aim of this narrative review was to summarize evidence of the nutritional status and dietary habits in children and the link with environmental sustainability.

KEY MESSAGE

Optimizing nutrition in infancy and establishing healthy lifestyles from the preschool years might help to reduce the risk of overweight, and all the disorders related, respecting the sustainability dimension.

Nutritional and health behaviour predictors of the weight gain during the COVID-19 pandemic

Purpose

This study aims to examine the effects of the COVID-19 pandemic on the body weight, nutritional habits, physical activity, and food consumption of adults living in Turkey and evaluate the effects of changes in these health behaviours on body weight.

Methods

A cross-sectional study was conducted with an online questionnaire. Data were collected through social media platforms using the snowball sampling method. A self-reported questionnaire included socio-demographic information, anthropometric data, dietary habits, food consumption, and lifestyle changes. In this study, 4181 people were included. Logistic regression analysis was used to evaluate the variables associated with the increase in body weight.

Results

The findings obtained in this study showed that the bodyweight of 58.5% of the participants increased during the COVID-19 pandemic, and this increase was the highest (66.3%) among the obese. The rate of those who stated that their physical activity decreased was 69.5%. The foods consumed the most by individuals were homemade desserts (54%), nuts (53.8%) and fresh fruits (52.3%). Those whose serving size increased [OR = 4.98 (3.76–6.60)], those whose physical activity decreased or increased [OR = 2.94 (2.38–3.63) or 2.52 (1.84–3.45), respectively], and those whose number of main meals consumed increased [OR = 2.17 (1.72) − 2.75)], those with increased consumption of white bread (OR = 1.63 (1.20–2.22) and those with increased consumption of packaged sweet products [OR = 1.53 (1.23–1.89)] were more likely to gain weight.

Conclusion

The results of this study show that there are significant changes in the body weight, physical activities, and eating habits of the participants during the COVID-19 pandemic. It is necessary to provide and follow-up specific guidance and support services for different groups to protect public health, improve and prevent nutrition-related diseases.

Nutritional Aspects of People Living with HIV (PLHIV) Amidst COVID-19 Pandemic: an Insight

PURPOSE OF REVIEW

This review elaborates the role of malnutrition in PLHIV (people living with HIV) in the context of COVID-19 and emphasis the need of supplementation, dietary intervention, and nutritional counselling in the post-COVID era. One of the most critical challenges among HIV/AIDS patients is malnutrition since it weakens the immune system and increases risk to opportunistic infections. In HIV (human immunodeficiency virus) infection, weight loss is prevalent due to reduced nutritional consumption, malabsorption, abnormal metabolism, and antiretroviral therapy. Sufficient nutrition is required for optimal immune function, as a result, food therapy is now considered an important adjuvant in the treatment of HIV patients.

RECENT FINDINGS

Nutritional intervention, such as the use of dietary supplements, can help to prevent nutrient deficiency, lowering the death risk among malnourished HIV population. Immunocompromised individuals are at very high risk for COVID-19 and malnutrition increases the risk of infection by multiple folds. Interventions, such as nutrition education and counselling are important, to improve the condition of HIV Patients by optimising their nutritional status.

SUMMARY

A balanced diet should be one of the most important priorities in preventing PLHIV against the potentially deadly consequences of COVID-19. It is to be ensured that HIV-positive persons continue to get enough and appropriate assistance, such as nutrition and psychological counselling, in the context of COVID-19 infection. The use of telemedicine to maintain nutritional intervention can be beneficial. To meet their nutritional needs and minimise future difficulties, PLHIV infected with COVID-19 should get specialised nutritional education and counselling.

Correlates of metabolic syndrome in patients with depression: A study from north-western India

BACKGROUND AND AIMS

Metabolic syndrome (MS) is found to be prevalent in patients with mental illness including depression. Data is sparse on the role of lifestyle factors on MS in depression.

METHODS

This study was aimed to assess correlates of MS in patients with depression.

METHODOLOGY

Three hundred eighty-two patients with depressive disorders were assessed for the prevalence of MS by using modified National Cholesterol Education Program- Adult Treatment Panel-III criteria (NCEP ATP-III). Their illness severity, functionality, physical activity and nutritional habits were also assessed.

CONCLUSIONS

Majority of patients with depression (82.2%) were drug naive. One-fourth of the patients had metabolic syndrome (27.7%). Additionally, other 59% of patients had one or two metabolic abnormalities and one-third of patients were obese. Lower high density lipoprotein cholesterol level was the most common abnormality (65%), while abnormal blood pressure was the least common abnormality (18%). Significant correlates of MS were greater age, and age at onset of depression, greater illness duration, lesser physical activity and lower nutritional score.

CONCLUSION

Nearly one-fourth of patients with depression had MS; another three-fifth of patients had one or two metabolic abnormalities. MS was more commonly seen with sedentary lifestyle and poor nutritional habits. It calls for comprehensive assessment and timely management of cardiovascular risk factors as well as lifestyle factors in depression.

Listeriolysin O antibodies detection in pregnant women: results from an Italian pilot study

BACKGROUND

Listeriosis is a rare infection affecting primarily pregnant women, the elderly and individuals with a weakened immune system and is caused by the ubiquitous bacterium Listeria monocytogenes. Infection during pregnancy can cause severe consequences especially for the fetus, leading to sepsis, premature delivery, stillbirth and miscarriage.

STUDY DESIGN

A pilot observational study has been conducted in order to establish the prevalence of seroconversion of specific antibodies against a peculiar toxin belonging to L. monocytogenes, listeriolysin O (LLO), in a population of pregnant women from Senigallia (Central Italy) and to find correlations between anti-LLO antibodies seropositivity and health and nutritional information. A total of 60 women were screened for anti-LLO antibody positivity and interviewed during their pregnancies. Statistical analyses were performed to evaluate antibody prevalence in serum samples and potential risk factors.

RESULTS

The seroprevalence resulted 18% (95% CI, 8.2 - 27.7%), corresponding to 11 pregnant women. Categorical principal component analysis and hierarchical cluster analysis revealed a significant correlation between anti-LLO positivity and gastrointestinal pain events and vomit, fever and diarrhea episodes, and a possible association with consumption of pre-cooked meal. No significant correlation was observed in women with a previous miscarriage or with miscarriage cases in their families.

CONCLUSIONS

Findings from this pilot study will be used to design a wider study focused on the prevalence of Listeria-specific antibodies in pregnant women and could allow to the identification of nutritional and behavioral habits related to Listeria infection which could lead to significant clinical implications.

Perceptions of Success in Bariatric Surgery: a Nationwide Survey Among Medical Professionals

INTRODUCTION

Various definitions for bariatric surgery (BS) success exist, with weight loss and comorbidity resolution outcomes being the most prominent. The study's aim was to compare how various healthcare professionals perceive success in BS.

METHODS

A 29-item, 10-point Likert scale online survey was distributed via email to Israeli healthcare professionals involved in the different BS aspects using common national professional organizations. These included bariatric surgeons, dietitians, social workers, psychologists, psychiatrists, primary care physicians, gastroenterologists, and nurses. Statement relevancy to BS success was rated. An item was classed as "very important" for BS success if at least 70% of participants rated it 8 or higher in each subgroup. Inter-observer agreement was calculated using kappa statistics. Data on specific occupation, years-in-practice, and major workplace were collected as well.

RESULTS

A total of 155 responses was obtained. The majority of respondents were dietitians (34.8%, n = 54), followed by bariatric surgeons (31.0%, n = 48) and nurses (14.8%, n = 23). Most respondents work mainly at public hospitals (32.9%, n = 51), followed by private hospitals (26.5%, n = 41). The mean years-in-practice among all healthcare professionals was 8.5 ± 8.5 years. Overall inter-observer agreement for prioritized items in accordance to BS success among all health professional subgroups was fair (Fleiss kappa = 0.278, P < 0.001), while dietitians and mental health specialists showed the highest agreement rate (Cohen's kappa = 0.592, P < 0.001).

CONCLUSION

The study highlights the various views on defining BS success by different healthcare professionals, although there was some overlap of core outcomes prioritized by all professionals. International uniform definitions for BS success are required.

Gene-diet-related factors of hyperglycaemia in postmenopausal women

As ageing and increased body fat are the signs of insulin resistance, we have studied whether the presence of Pro12Ala and C1431T of peroxisome proliferator-activated receptor gamma 2 gene and Trp64Arg of beta 3-adrenergic receptor gene may predispose to the hyperglycaemia development in postmenopausal women, who have never undergone hypoglycaemic treatment. The distributions of selected allele and genotype frequencies were determined by the PCR–RFLP method in normo- and hyperglycaemic, who have never been diagnosed and treated for diabetes mellitus were measured. The amount of body fat and lean body mass (LBM) were assessed by the bioimpedance method and nutritional habits by 7-day dietary recall. There were no differences between the distribution of genotypes and the allele frequencies of the Pro12Ala, C1431T and Trp64Arg polymorphisms in normo- and hyperglycaemic women. Hyperglycaemic women were characterized by visceral obesity, hypertension, higher serum insulin and triglycerides, higher intake of fat and lower consumption of complex carbohydrates and B vitamins. Normoglycaemic women with Pro12Pro polymorphism acquired higher energy from dietary fat (p < 0.0276) and lower energy from carbohydrates (p < 0.0480) than normoglycaemic Ala12 carriers. Subjects with Pro12Pro polymorphism and LBM > 58% of total body mass or with Trp64Trp and normal triglycerides have higher chance of normoglycaemia. Genotyping for Pro12Ala and Trp64Arg polymorphism in postmenopausal women may have the clinical benefit of predicting hyperglycaemia, thereby contributing to the prevention of diabetes mellitus development in the future. However, not only the genetic background but also the dietary habits (intake of fat, carbohydrates and B vitamins) determine the risk of hyperglycaemia.

Selected nutritional habits of teenagers associated with overweight and obesity

INTRODUCTION

A balanced diet is at the heart of healthy growth and development of children and youth, whereas inappropriate eating habits considerably influence the incidence of disorders connected with nutrition, including overweight and obesity. This paper aims at studying nutritional factors of 18-year-old secondary school youth in the urban environment and their effect on the incidence of overweight and obesity.

MATERIALS AND METHODS

The survey was conducted among 1,999 secondary school students chosen at random. The research tool consisted an original survey questionnaire. The measurements of respondents' height and body mass provided data for calculating the body mass index.

RESULTS AND CONCLUSION

The percentage of youth with deficient body mass was estimated at 8.4%. The percentage of normal weight students in the surveyed group was estimated at 77.6%. Overweight and obesity characterized 14.0% of the total number. As many as 21.8% of overweight and obese respondents would eat one or two meals as opposed to 16.8% of normal weight students. Three-fourths of the surveyed students would eat breakfast regardless of their nutritional habits. Lunch is eaten by 52.9% of normal weight 18-year-olds and 46.1% of overweight and obese students. The analysis of mealtimes suggests that overweight and obese students would have their breakfast and dinner at later hours than the rest of the surveyed. More than half of the participating students failed to eat lunch (53.9%), and one in four students within this group resigned from supper. Girls would eat fruit and vegetables more frequently than boys several times a day. The percentage of persons in the surveyed groups who would eat fast foods on a daily basis was similar regardless of their nutritional status. Sweetened carbonated beverages would be drunk more often by overweight and obese boys (81.2%) as compared with boys with proper body mass (75.8%). The same type of beverages would be popular with two-thirds of girls, and this result was similar regardless of their nutritional status. About 44.2% of overweight and obese girls and 20% of girls with proper body mass attempted to lose weight, and 5.7% of boys tried to go on a diet. Eating limitations were declared by 16.5% of overweight and obese boys and ca. 3% of normal weight boys.

CONCLUSION

Within the surveyed group of youth, it was possible to indicate eating errors primarily consisting in irregular eating, too low a number of meals during the day, particularly skipping breakfast, which took place more frequently among overweight and obese students rather than normal weight ones. The survey points to the insufficient intake of vegetables and fruit as opposed to salty and sweet meals. It is essential to convey the knowledge on the causes of overweight and obesity as well as rules of a healthy diet as factors preventing civilization diseases.

Modularising ontology and designing inference patterns to personalise health condition assessment: the case of obesity

BACKGROUND

The public health initiatives for obesity prevention are increasingly exploiting the advantages of smart technologies that can register various kinds of data related to physical, physiological, and behavioural conditions. Since individual features and habits vary among people, the design of appropriate intervention strategies for motivating changes in behavioural patterns towards a healthy lifestyle requires the interpretation and integration of collected information, while considering individual profiles in a personalised manner. The ontology-based modelling is recognised as a promising approach in facing the interoperability and integration of heterogeneous information related to characterisation of personal profiles.

RESULTS

The presented ontology captures individual profiles across several obesity-related knowledge-domains structured into dedicated modules in order to support inference about health condition, physical features, behavioural habits associated with a person, and relevant changes over time. The modularisation strategy is designed to facilitate ontology development, maintenance, and reuse. The domain-specific modules formalised in the Web Ontology Language (OWL) integrate the domain-specific sets of rules formalised in the Semantic Web Rule Language (SWRL). The inference rules follow a modelling pattern designed to support personalised assessment of health condition as age- and gender-specific. The test cases exemplify a personalised assessment of the obesity-related health conditions for the population of teenagers.

CONCLUSION

The paper addresses several issues concerning the modelling of normative concepts related to obesity and depicts how the public health concern impacts classification of teenagers according to their phenotypes. The modelling choices regarding the ontology-structure are explained in the context of the modelling goal to integrate multiple knowledge-domains and support reasoning about the individual changes over time. The presented modularisation pattern enhances reusability of the domain-specific modules across various health care domains.

Effect of Nutritional Habits on Dental Caries in Permanent Dentition among Schoolchildren Aged 10-12 Years: A Zero-Inflated Generalized Poisson Regression Model Approach

BACKGROUND

The aim of this study was to assess the associations between nutrition and dental caries in permanent dentition among schoolchildren.

METHODS

A cross-sectional survey was undertaken on 698 schoolchildren aged 10 to 12 yr from a random sample of primary schools in Kermanshah, western Iran, in 2014. The study was based on the data obtained from the questionnaire containing information on nutritional habits and the outcome of decayed/missing/filled teeth (DMFT) index. The association between predictors and dental caries was modeled using the Zero Inflated Generalized Poisson (ZIGP) regression model.

RESULTS

Fourteen percent of the children were caries free. The model was shown that in female children, the odds of being in a caries susceptible sub-group was 1.23 (95% CI: 1.08-1.51) times more likely than boys (P=0.041). Additionally, mean caries count in children who consumed the fizzy soft beverages and sweet biscuits more than once daily was 1.41 (95% CI: 1.19-1.63) and 1.27 (95% CI: 1.18-1.37) times more than children that were in category of less than 3 times a week or never, respectively.

CONCLUSIONS

Girls were at a higher risk of caries than boys were. Since our study showed that nutritional status may have significant effect on caries in permanent teeth, we recommend that health promotion activities in school should be emphasized on healthful eating practices; especially limiting beverages containing sugar to only occasionally between meals.

Nutritional habits among high-performance endurance athletes

BACKGROUND AND OBJECTIVE

For athletes, the main purpose of nutrition is to ensure the compensation of increased energy consumption and the need for nutrients in the athlete's body, thereby enabling maximum adaptation to physical loads. The aim of this study was to determine the habits of highly trained endurance athletes depending on sports type, sex and age in order to improve the planning and management of the training of athletes using targeted measures.

MATERIALS AND METHODS

In 2009-2012, the dietary habits of 146 endurance athletes were analyzed. The actual diet of Lithuania endurance athletes was investigated using a 24-h dietary survey method. Data on the athletes' actual diet were collected for the previous day.

RESULTS

It was found that 80.8% of endurance athletes used lower-than-recommended amounts of carbohydrates in their diet, and more than 70% of athletes used higher-than-recommended levels of fat, saturated fatty acids, and cholesterol. The diet of female athletes was low in carbohydrates, dietary fiber, protein, omega-3 fatty acids, B vitamins, potassium, calcium, phosphorus, iron, manganese, and zinc. Athletes aged 14-18 years tended to consume quantities of protein that were either lower than recommended or excessive.

CONCLUSIONS

The diet of highly trained endurance athletes does not fully meet their requirements and in this situation cannot ensure maximum adaptation to very intense and/or long-duration physical loads. The diet of highly trained endurance athletes must be optimized, adjusted and individualized. Particular attention should be focused on female athletes.

The prevalence of iron deficiency anemia in a Saudi University female students

The study aims to determine the prevalence of anemia in apparently healthy university female students. This study was conducted in 2007–2008 at Taibah University and a total of 268 female students participated in this research. In order to assess iron deficiency and iron deficiency anemia, the venous blood samples were collected from consecutive female students at the medical center of Taibah University excluding those already on iron supplementation for iron-deficiency anemia. One hundred and seventy-one (64%) students were found to be anemic. The overall prevalence of mild (10–11 g/dL), moderate (7–10 g/dL), and severe (Hb <7 g/dL) anemia was 45%, 49%, and 6%, respectively. Out of the anemic students, 81% showed microcytic (MCV <80 fL) and 1.6% had macrocytic (MCV >96 fL) variety. The results of this study warrant further evidence-based surveys on a larger scale to validate these findings and eventually set a stage to develop well-organized educational and nutritional programs to safeguard and improve the nation’s health. The high prevalence of iron deficiency anemia in the present study might be related to life style of female students as well as to their dietary habits. It is recommended that female students never skip breakfast as it is essential for their cognitive functions and physical activities.

Effects of dietary intervention in young female athletes with menstrual disorders

Background

The aim of this study was to evaluate the influence of three months of dietary intervention on menstrual cycle in young female athletes with amenorrhea or oligomenorrhea.

Methods

From forty-five female professional athletes with menstrual irregularity that were recruited thirty-one, aged 18.1 ± 2.6 years, completed the study and were analyzed. Hyperprolactinemia, thyroid dysfunction, primary ovarian failure and hyperandrogenism were excluded in the study participants. The subjects started intense training at the age of 11.2 ± 3.5 years and continued during next 6.8 ± 3.3 years. Energy and nutrients intake, total energy expenditure, energy availability and body composition as well as serum concentrations of LH, FSH, 17 – beta estradiol and progesterone were measured at the beginning of the study and after three months of individualized dietary intervention.

Results

Following three months of dietary intervention significant increase in energy intake (2354 ± 539 vs. 258 8 ± 557 kcal, P = 0.004) and energy availability (28.3 ± 9.2 vs. 35.8 ± 12.3 kcal/kg FFM/d, P = 0.011) was observed as well as improved energy balance (−288 ± 477 vs. -51 ± 224 kcal/d, P = 0.002). Though no changes in BMI and body composition were noted but significant rise in LH concentrations (3.04 ± 1.63 vs. 4.59 ± 2.53 mIU/ml, P = 0.009) and LH to FSH ratio (0.84 ± 0.56 vs. 0.96 ± 0.52, P = 0.001) was achieved, but no restoration of menstrual cyclicity.

Conclusions

This report provides further support for the role of energy deficiency in menstrual disorders among young female athletes and the benefits of an adequate energy intake and energy availability on hormones concentration. Continuation controlled dietary intervention is needed to assess the extent to which long-term improvement in the nutritional status results in improvements in the hormonal status of female athletes, to an extent that would allow the regulation of the menstrual cyclity.
