Screening and treatment of obesity in school health care - the gap between clinical guidelines and reality

Successful Weight Loss in Adolescents with Overweight or Obesity Using a Swallowable Intragastric Balloon and Nutritional Oversight

PURPOSE

Medical devices benefit patients living with overweight or obesity, but studies in the adolescent population are lacking. The goal of this study was to collect information on the performance and safety of a swallowable intragastric balloon program (SGBP) in adolescent patients.

MATERIALS AND METHODS

Data were collected retrospectively on patients aged 15 to 17 years with body mass index (BMI) ≥ 27 kg/m2 who received the swallowable intragastric balloon (SGB) and associated lifestyle and nutritional change program. Patients had not responded to previous dietary and behavioral modification weight loss treatments and elected to undergo SGBP. The SGB was swallowed and filled with 550 mL of distilled water in an outpatient setting, and a multidisciplinary team delivered a lifestyle/nutritional change program. Mean % total body weight loss (%TBWL) was calculated for each patient compared with baseline.

RESULTS

A total of 91 patients, 69 (75.8%) female and 22 (24.2%) male, underwent SGBP and completed follow-up through SGB passage at 4 months. Baseline mean ± SD age, weight, and BMI were 16.4 ± 0.77, 99.70 ± 21.33 kg, and 35.60 ± 5.59 kg/m2, respectively. After 4 months, mean weight and BMI were 86.37 ± 18.83 kg and 30.86 ± 5.16 kg/m2 respectively; %TBWL was 13.05 ± 7.64 (1-sided t-test, p < 0.0001). Most (80, 87.9%) reported no adverse events; 11/91 (12.1%) experienced an adverse event. Of these, 9/91 (9.9%) experienced nausea and/or vomiting; 1/91 (1.1%) reported abdominal pain only; 1/91 (1.1%) reported flatulence only. There were no serious adverse events or premature device removals.

CONCLUSION

The SGBP provides safe and effective short-term weight loss in adolescents living with overweight and obesity.

In search of factors related to migration affecting children's health - an analysis of documents guiding health visits within the Swedish school health services

BACKGROUND

Migration affects the health of children worldwide. Therefore, school nurses who encounter these children as part of their everyday practice need support from guidelines on how to promote the health of children who have migrated or whose parents have migrated. Yet knowledge regarding such content in guidelines of school nursing practice is sparse. Therefore, this study aims to investigate how municipal and regional guidelines and health questionnaires used in health visits in the Swedish school health services include factors related to migration that affect children's health.

METHODS

A document analysis of municipal and regional guidelines and health questionnaires guiding school nurses' practice in health visits was conducted during the autumn of 2020. In total, 687 guidelines and health questionnaires were analyzed using deductive content analysis.

RESULTS

The results show that municipal and regional guidelines and health questionnaires used in health visits in the Swedish school health services include content on many factors related to migration that affect children's health. Yet the content was limited, and none was found on factors related to discrimination based on ethnicity or origin.

CONCLUSION

Guidance related to promoting the health of children who have migrated or whose parents have migrated should include all factors affecting these children's health. Therefore, to strengthen school nurses' evidence-based practice, guideline development might be needed, although guidelines and health questionnaires exist and include content on many factors related to migration affecting the health of children in order to provide equitable healthcare for all children, regardless of country of origin.

Weight transitions and psychosocial factors: A longitudinal cohort study of Finnish primary school children with overweight

•

Children most probably stayed in their initial weight category.

•

Probabilities of transitioning across weight categories differ between genders.

•

Girls of nuclear families transition to obesity at a lower rate than their peers.

•

Experiences of crises and bullying are related to obesity development among boys.

•

Multistate models are useful for analyzing childhood obesity development.

For targeted prevention and treatment of childhood obesity, primary health care needs methods to identify children potentially developing obesity. The objectives of this study were to examine transitions across weight categories and their association with psychosocial family- and school-related factors, data on which were retrieved from health records. This longitudinal cohort study comprised 507 Finnish children with overweight, identified from a random sample of 2000 sixth graders in Helsinki in 2013. We applied Markov multistate models to analyze the transition rates over six primary school years between BMI SDS categories of normal weight, overweight and obesity, as assessed by Finnish BMI-for-age reference, and to examine relations between transition rates and family- and school-related factors. Among 3116 pairs of consecutive growth measurements from 225 girls and 282 boys aged 6–14, 719 transitions from weight category to another occurred. The highest 1-year probabilities were 0.76 for girls to stay in overweight and 0.80 for boys to stay in obesity. Transitions from normal weight to overweight and from obesity to overweight were more probable than vice versa. Transitions from overweight into obesity were among girls associated with older age (HR 2.63) and divorced or single parents (HR 2.29), as well as among boys with experiences of crises (HR 2.40) and being bullied (HR 1.66). Factors identifiable in school health care and associated with the probability of transition towards obesity should be considered when planning individual support and intervention programs.

Changes in Thyroid and Glycemic Status and Food Intake in Children with Excess Weight Who Were Submitted for a Multi-Component School Intervention for 16 Months

We investigated if children with excess weight who submitted to two types of intervention at school for 16 months showed improvements in thyroid and glycemic function and food intake. Children (8-11 years) with a body mass index-for-age (BMI/A) of ≥1 Z score were divided into two groups: Treatment 1 (n = 73) involved motivation to adopt healthier lifestyle; Treatment 2 (n = 103) involved performing weekly nutritional education, motivational, and physical activities at school. A semi-quantitative food frequency questionnaire was used. The delta BMI/A were similar after 16 months; Treatment 1 showed higher decrease in thyroid-stimulating hormone (TSH; median (range)): -0.45 (-3.19 to 2.17) and 0.06 (-4.57 to 1.63) mIU/L, p = 0.001), FreeT3 (-0.46 (-2.92 to 1.54) and -0.15 (-2.46 to 1.38) pmol/L, p = 0.038), and FreeT4 -1.41 (-6.18 to 3.47) and -0.90 (-4.89 to 2.96) pmol/L, p = 0.018), followed by decrease in energy intake (7304 (6806 to 7840) and 8267 (7739 to 8832) kJ, Ptreatment = 0.439, Ptime <0.001, interaction group-time p < 0.001), macronutrients and sugar. A positive correlation between FreeT3 and BMI/A, and a negative correlation with FreeT4 and insulin were found at baseline (r 0.212, p < 0.01; r -0.155, p < 0.01, respectively) and follow-up (r 0.222, p < 0.01; r -0.221, p < 0.01). The decrease in overall diet and particularly sugar intake was accompanied by a greater reduction in TSH and FreeT3 in Treatment 1, demonstrating the impact of dietary intake on thyroid function.

Distinct age-related patterns of overweight development to guide school healthcare interventions

AIM

We aimed to identify groups of primary school children with similar overweight development, reveal age-related patterns of overweight development in the resulting groups and analyse overweight-related school healthcare interventions.

METHODS

This retrospective longitudinal register study utilised electronic health records from six primary school years. From a random sample of 2000 sixth graders, we derived a study cohort of 508 children meeting criteria for overweight at least once during primary school. We investigated how many different groups (latent classes) of children with similar weight development would emerge by applying flexible latent class mixed models on body mass index standard deviation score. We also explored the resulting groups with respect to offered overweight-related interventions.

RESULTS

Per child, the data consisted in median 7 growth measurements over 5.4 years. We identified five overweight development groups for girls and four for boys. The groups converged temporarily around age 10 after which only some continued into obesity. School nurses and physicians offered overweight-related interventions to children with obesity, less to children gaining weight or with overweight.

CONCLUSION

Obesity prevention might benefit from awareness of typical overweight development patterns when designing intervention studies or planning and timing multidisciplinary school health check programmes.
