[Prevalence of obesity and diabetes in Spain. Evolution in the last 10 years]

The prevalence of overweight and obesity has been increasing in recent decades, worldwide and in all age groups, including children and adolescents. In Spain, the prevalence of overweight and obesity is high and is expected to increase in the coming years. The World Atlas of Obesity suggests that in 2035 the prevalence of obesity in Spain will be high or very high, both in adults and children, following the worldwide trend. The prevalence of diabetes and obesity in Spain is higher in older people, especially those aged 65 and over. In the case of Spanish children and adolescents, there seems to be a stabilization in the rates of overweight and obesity, with the exception of the group of girls aged 10-15 years, where a gradual increase has been observed in the last 10 years.

The effects of diet quality and dietary acid load on insulin resistance in overweight children and adolescents

INTRODUCTION

This study aimed to investigate the association of diet quality (DQ) and dietary acid load (DAL) with insulin resistance (IR) in overweight children and adolescents.

MATERIALS AND METHODS

The study was conducted on 135 overweight participants aged 6-17 years. DQ was assessed using the Healthy Eating Index 2015 (HEI-2015) and the HEI-2015-TUBER, revised in accordance with the Turkey Dietary Guidelines (TUBER). Estimation of DAL was made calculating the potential renal acid load (PRAL) and net endogenous acid production (NEAP) scores.

RESULTS

The HEI-2015-TUBER score was lower in those with IR than in those without IR (p=0.021). Higher PRAL and NEAP scores were found in those with IR (p=0.060 and p=0.044, respectively). Moreover, a one-unit increase in the HEI-2015-TUBER score and the DAL score was associated with a reduction of 4.2% and a rise of approximately 3% in IR risk, respectively.

CONCLUSIONS

Healthy eating habits in overweight paediatric groups may help to reduce the IR risk, improving DQ and decreasing DAL.

Does obesity really affect renal transplantation outcomes?

INTRODUCTION

Kidney transplantation is the treatment of choice for patients with stage 5 chronic kidney disease (CKD). About 60% of CKD patients are overweight or obese at the time of kidney transplantation, and post-transplant obesity occurs in 50% of patients, with a weight gain of 10% in the first year and high risk of cardiovascular mortality. Obesity is associated with an increased risk of delayed graft function (DGF), acute rejection, surgical complications, graft loss and mortality. The aim of this study is to assess the clinical evolution of obese and overweight patients that have received a kidney transplant, based on short- and long-term complications associated with a higher BMI.

MATERIAL AND METHODS

A descriptive, observational, cross-sectional study was conducted with 104 kidney or pancreas-kidney transplant patients between March 2017 and December 2020, with a follow-up until April 2021. For comparative analysis, patients were grouped according to BMI.

RESULTS

Mean age was of 56.65 years, 60.6% male and 39.4 % female. Overweight patients experienced prolonged surgeries, more surgical wound dehiscence, delayed graft function, hernias, proteinuria and more indications for renal biopsies. Additionally, obese patients displayed more DGF, indications for renal biopsies, proteinuria, development of diabetes mellitus, atrial fibrillation and needed prolonged hospital stays.

CONCLUSIONS

Despite a high prevalence of comorbidity in the overweight and/or obese population, we found no reduction in patient and/or graft survival. However, longer follow-up is needed.

[Impact of attend to day care associated with healthy weight in infants and preschoolers]

Background

Being overweight affects millions of infants and preschoolers in the world, affecting their quality and life expectancy. Exposure to day care centers may play an important role in preventing unhealthy weight (UW).

Objective

To point out the prevalence and association of day care exposure and other factors associated with UW in infants and preschoolers.

Methods

An analytical cross-sectional study was carried out. Infant population aged 6-47 months without comorbidities that compromised their nutritional status were included, and those with formal childcare different from the selected day care were excluded. Exposure to day care, and other factors (perinatal, physical activity, nutritional, and familiar) were evaluated. A z score > 1 SD was considered UW. Prevalence, odds ratios (OR), 95% confidence intervals (95%CI) and adjusted RM by low birth weight, initiation of complementary feeding, consumption of sugary drinks, daytime naps, maternal nutritional status, and family income quintile through logistic regression.

Results

The overall prevalence of UW was 17.84% (95%CI: 14.93-21.16), 11.84 (95%CI: 8.54-16.14) for children exposed to day care, and 23.78% (95%CI: 19.21-29.02) in unexposed infant population, showing significant differences between both prevalences (p < 0.001). The adjusted OR for UW presentation was 0.39 (95% CI: 0.23-0.66).

Conclusions

Exposure to IMSS day care has shown to be a possible protective environment against the development of a UW.

Prevalence of childhood obesity in Spain and its relation with socioeconomic status and health behaviors: Population-based cross-sectional study

OBJECTIVES

This study aims to assess the current state of childhood overweight and obesity in Spain, and its relationship with socioeconomic status and health-related behaviors.

METHODS

Population-based cross-sectional observational study, based on the 2017 National Health Survey in minors in Spain. This study included all children surveyed who were aged 1-14 years. Childhood obesity was estimated from the z-score of the body mass index.

RESULTS

The study included 4882 children aged 1-14 years (mean 7.5). The prevalence of obesity was 18.6% (95% confidence interval [CI] 18.5-18.7), while 13.5% (95% CI 13.4-13.6) were overweight. These figures represent over a million children in Spain who are obese and nearly 750,000 who are overweight. A north-south geographic gradient was apparent, with higher prevalence of unhealthy body weight in southern Spain. Factors associated with childhood obesity were low socioeconomic status, poor diet and sedentarism, among others.

CONCLUSIONS

Childhood overweight in Spain is strongly associated with socioeconomic status and other factors such as diet and sedentarism. Multidisciplinary public health interventions are needed to reduce this serious health problem in children.

Prevalence rates of overweight and obesity and their associations with cardiometabolic and renal factors. SIMETAP-OB study

INTRODUCTION

Excess weight is a major health problem. Aims of this study were to determine the prevalence rates of overweight and obesity, and to compare their associations with cardiometabolic and renal risk factors between obese and non-obese populations, and between overweight and non-overweight populations.

METHODS

Cross-sectional observational study conducted in Primary Care. Population-based random sample: 6,588 study subjects between 18 and 102 years of age (response rate: 66%). Crude and sex- and age-adjusted prevalence rates of overweight and obesity were calculated, and their associations with cardiometabolic and renal variables were assessed by bivariate and multivariate analysis.

RESULTS

The age- and sex-adjusted prevalence rates of overweight and obesity were 36.0% (42.1% in men; 33.1% in women) and 25.0% (26.2% in men; 24.5% in women), respectively. These prevalences increased with age, and were higher in men than in women. Fifty-two percent (95%CI: 50.0-53.9) of the overweight population and 62.3% (95%CI: 60.1-64.5) of the obese population had a high or very high cardiovascular risk. Abdominal obesity, physical inactivity, prediabetes, hypertension, hypertriglyceridemia, and low HDL-C were independently associated with both entities. Furthermore, diabetes was independently associated with overweight and hypercholesterolemia with obesity.

CONCLUSIONS

The prevalence of overweight and obesity was 61.0% (68.4% in men and 59.0% in women). More than half of the overweight population and nearly two-thirds of the obese population had a high cardiovascular risk. Hyperglycemia, physical inactivity, hypertension, hypercholesterolemia, low HDL-C, and hypertriglyceridemia were independently associated with overweight and obesity.

[Double diabetes mellitus. Double challenge for the exercise prescription. Systematic review]

Double diabetes (DD) refers to patients with type 1 diabetes who have developed insulin resistance. The objective of this review is to update relevant information on the prescription of physical activity, pharmacological adjustments and consumption of carbohydrates in DD. A systematic search for scientific articles was carried out in the following databases: PubMed, Cochrane, EBSCO, WoS, ScienceDirect and Medline. The evidence analyzed shows that both physical activity (PA) and physical exercise (PE) are essential to achieve metabolic control in people with DD. Physiological considerations such as: insulin adjustments, insulin injection sites, time to perform PA and PE, absolute and relative contraindications are essential to avoid complications, especially hypoglycemia.

Prevalence of overweight and obesity in Aragón and variations according to health determinants

INTRODUCTION

Childhood obesity is a serious global health problem that is continuously increasing worldwide. Many studies suggest that socioeconomic factors are related to the development of obesity. The objective of our study was to analyse the prevalence of overweight and obesity in Aragón, calculated applying the World Health Organization (WHO) growth standards, and to study its association with socioeconomic factors.

MATERIAL AND METHODS

We collected data for the entire paediatric population of Aragón aged 2-14 years. We classified each child as normal weight, overweight or obese based on the body mass index. We calculated prevalences by province and basic health care zone. To analyse differences in relation to social inequalities, we used the Aragón deprivation index as an indicator of socioeconomic status.

RESULTS

The final sample consisted of 161 335 children aged 2-14 years, 51% male and 49% female. The overall prevalence of excess weight was 31.1% (17.7% overweight and 13.3% obesity) and was significantly higher in boys. We found a high frequency of under-recording in health records (65%). There was a direct association between the deprivation index and the prevalence of obesity and overweight throughout Aragón, with a significant strong correlation in urban areas, where socioeconomic factors explained up to 66.4% of obesity and 48.9% of body weight excess.

CONCLUSIONS

In Aragón, the prevalence of obesity and excess weight is high and associated with low family socioeconomic status.

Body mass index in offspring of mothers with diabetes mellitus: follow-up at 2, 4, 6, and 8 years of age

Background

Offspring of mothers with diabetes mellitus (DM) during pregnancy may be at high risk for developmental alterations. This study aimed to identify the effects of maternal pre- and gestational diabetes on the body mass index of infants and children at two, four, six, and eight years of age.

Methods

We studied children of mothers with type 1, type 2, and gestational diabetes and a control group. Maternal and neonatal variables were analyzed for associations with children overweight/obesity.

Results

Mothers with DM were older than controls (32 ± 6 vs. 22 ± 6 years, p < 0.001). The frequency of preeclampsia in mothers with DM was 28%. Gestational age and weight at birth were lower in infants from the groups of mothers with DM in comparison with controls (32.8 ± 3.1 vs. 36.4 ± 2.2 weeks, p < 0.001, and 1,637 ± 600 vs. 2,208 ± 518 g, p < 0.001, respectively). At 8 years of age, 47% of the offspring of mothers with DM type 2 had overweight/obesity (odds ratio (OR 8.25) 95% confidence interval (CI) 1.3-51, p = 0.01), while 27% of offspring of mothers with type 1 DM had overweight/obesity, and 10% of offspring of mothers with gestational diabetes presented overweight/obesity.

Conclusions

Offspring of pre-gestational DM mothers have a higher risk to develop overweight/obesity, as was observed with follow-up until school age, for which they require continuous vigilance.

Study of gastroesophageal reflux. Interpretation of functional tests in the obese patient

Overweight and obesity are a public health problem and in 1997 obesity was recognized as a global epidemic by the World Health Organization (WHO). Overweight and obesity affect almost 60% of adults and one in three children in Europe according to the most recent WHO report. Objectively, gastroesophageal reflux disease (GERD) is defined as the presence of characteristic esophageal mucosal damage assessed by endoscopy and/or the demonstra-tion of pathological acid exposure by reflux monitoring studies. The prevalence of GERD is increased in obese patients In overweight and obese patients, the clinical symptoms of GERD are especially present in the supine position and this correlates with more frequent episodes of nocturnal reflux in the 24-h pH monitoring, there is also an increase in the number of refluxes with content acid. In the population with symptoms, digestive endoscopy detects data of erosive esophagitis in 50% of patients, while 24-h pH-impedanciometry diagnoses 92% of patients with non-erosive reflux disease (NERD) The presence of persistent GERD in the mucosa affects esophageal motility and patients may develop ineffective esophageal motility-type disorders, so we will review the interpre-tation of the functional tests that determine motility, which is esophageal manometry, and those that determine reflux gastroesophageal, acid and non-acid, which is the pH measure-ment with or without 24-h impedanciometry.

Socioeconomic and gender inequalities in childhood obesity in Spain

INTRODUCTION

Childhood obesity is inversely associated with household socioeconomic status in high-income countries. Our aim was to explore the association between childhood weight status and household socioeconomic status in Spain in relation to family characteristics, perceptions and lifestyle habits and the school environment.

METHODS

We performed a descriptive analysis of child weight status according to family socioeconomic factors and mediating variables based on data from the ALADINO 2019 study in a sample of 16,665 schoolchildren representative of the population aged 6-9 years in Spain.

RESULTS

The prevalence of childhood obesity in households with low socioeconomic status (26.8% boys; 20.4% girls) was, in both sexes, twice as high as in those with higher socioeconomic status (12.1% boys; 8.7% girls). Unhealthy eating habits, sedentary lifestyles (mainly in girls) and the presence of screens in the bedroom (more prevalent in boys) were more frequent in school-aged children from low-income households. On the other hand, in the most disadvantaged households, a history of breastfeeding and physical activity (especially in girls) were less frequent. Similarly, schools attended by children from low-income households were less likely to have their own kitchens and indoor gymnasiums or offer sports activities.

CONCLUSION

A lower household socioeconomic status was associated with poorer dietary and physical activity habits and certain characteristics of the family and school environments that mediate the inverse association between household socioeconomic status and the prevalence of childhood obesity. Girls were less physically active and reported more sedentary lifestyles, while boys had greater access to screens. Interventions to combat childhood obesity should address the identified inequalities.

Differences in the temporal trends of childhood overweight and obesity in Spain in the 2011-2019 period by sex, age and socioeconomic level: results of the ALADINO study

INTRODUCTION

Childhood excess weight is a growing public health problem. The aim of this study was to assess temporal trends in the prevalence of overweight, obesity and central obesity in schoolchildren aged 6-9 years in Spain between 2011 and 2019 based on demographic and socioeconomic characteristics.

METHODOLOGY

The analysis included data from the 2011, 2015 and 2019 rounds of the cross-sectional observational and descriptive ALADINO study in schoolchildren of both sexes aged 6-9 years. We conducted a descriptive analysis of the trends in the prevalence of overweight and obesity (defined according to the criteria of the World Health Organization and the International Obesity Task Force) and of central obesity, in addition to associated demographic and socioeconomic variables.

RESULTS

Between 2011 and 2019, the prevalence of overweight (WHO criteria) decreased in boys aged 6, 7 and 8 years (by -5.4%, -5.7% and -5.3%, respectively) and boys whose parents had a higher educational attainment (by -5.3%). In relation to the socioeconomic level, overweight in boys declined at all income levels. However, between 2011 and 2019, both the prevalence of overweight in girls and the prevalence of obesity (applying the WHO and IOTF criteria) and the prevalence of central obesity in both sexes remained stable.

CONCLUSIONS

The prevalence of overweight and the prevalence of obesity in schoolchildren aged 6-9 years in Spain remain high. Between 2011 and 2019, the prevalence of overweight in children aged 6-8 years and in children whose parents had university degrees decreased, whereas obesity in boys, overweight and obesity in girls and central obesity in both sexes remained stable.

Diagnosis of nutritional status, dyslipidemia and associated risk factors in indigenous Yaqui schoolchildren

BACKGROUND

Malnutrition is a global problem that affects schoolchildren and can increase the risk of diseases in adulthood. Adult members of the Yaqui Indigenous group have been shown to have serious health problems, and Yaqui schoolchildren could therefore find themselves in a similar situation.

OBJECTIVE

To evaluate the nutritional status, lipid profile and associated factors in a sample of Yaqui schoolchildren.

MATERIAL AND METHODS

A total of 109 Yaqui schoolchildren who lived in their localities of origin were recruited. Anthropometric measurements were carried out, a venous blood sample was extracted in fasting conditions, and several questionnaires were applied.

RESULTS

The prevalence of overweight/obesity was 38.5%, with no cases of chronic malnutrition being recorded; 38.6% of the children had dyslipidemia. Fiber consumption was a protective factor against overweight/obesity, while fat intake was a risk factor. The physical activity score was found to be a protective factor against dyslipidemia, and the risk factors were BMI-for-age Z-scores, waist circumference, family history of dyslipidemia, educational level, and permanent employment.

CONCLUSIONS

Yaqui schoolchildren equally suffer from a high proportion of overweight/obesity and dyslipidemia. The associated factors may be useful for the design of contextualized interventions for this population.

Influence of obesity and overweight in surgical outcomes of adrenalectomy for primary adrenal disease: A cohort study of 146 cases

OBJECTIVE

To evaluate the impact of obesity and overweight on surgical outcomes in a large cohort of patients who underwent adrenalectomy due to benign or malignant primary adrenal disease.

METHODS

A retrospective single-center study of patients without history of active extraadrenal malignancy, with adrenal tumors operated on consecutively in our center between January 2010 and December 2022. Obesity was defined as a body mass index (BMI)≥30kg/m2 and overweight as BMI between 25.0 and 30.0kg/m2.

RESULTS

Of 146 patients with adrenal tumors who underwent adrenalectomy, 9.6% (n=14) were obese, 54.8% (n=80) overweight and 35.6% (n=52) normal weight. Obese patients had higher diastolic blood pressure (87.6±12.22 vs. 79.3±10.23mmHg, P=0.010) and a higher prevalence of dyslipidemia (57.1% vs. 25.8%, P=0.014) and bilateral tumors (14.3% vs. 3.1%, P=0.044) than non-obese patients. The rates of intraoperative and of postsurgical complications were similar between obese/overweight patients and patients with normal weight. However, a significantly higher rate of postsurgical complications (27.3% vs. 5.7%, P=0.009) and a longer hospital stay (5.4±1.39 vs. 3.5±1.78 days, P=0.007) were observed in patients with obesity than in non-obese patients. In the multivariant analysis, obesity, age, ASA>2 and tumor size were independent risk factors for postoperative complications, with obesity being the most important factor (OR 23.34 [2.23-244.24]).

CONCLUSION

Obesity and overweight are common conditions in patients who undergo adrenalectomy. Adrenalectomy is considered a safe procedure in patients with overweight, but it is associated with a higher risk of postsurgical complications and longer hospital stay in obese patients.
