Tidskriftsartikel (refereegranskat)abstract
- From 1985 to 2016, the prevalence of underweight decreased, and that of obesity and severe obesity increased, in most regions, with significant variation in the magnitude of these changes across regions. We investigated how much change in mean body mass index (BMI) explains changes in the prevalence of underweight, obesity, and severe obesity in different regions using data from 2896 population-based studies with 187 million participants. Changes in the prevalence of underweight and total obesity, and to a lesser extent severe obesity, are largely driven by shifts in the distribution of BMI, with smaller contributions from changes in the shape of the distribution. In East and Southeast Asia and sub-Saharan Africa, the underweight tail of the BMI distribution was left behind as the distribution shifted. There is a need for policies that address all forms of malnutrition by making healthy foods accessible and affordable, while restricting unhealthy foods through fiscal and regulatory restrictions.

- Body-mass index (BMI) has increased steadily in most countries in parallel with a rise in the proportion of the population who live in cities(.)(1,2) This has led to a widely reported view that urbanization is one of the most important drivers of the global rise in obesity(3-6). Here we use 2,009 population-based studies, with measurements of height and weight in more than 112 million adults, to report national, regional and global trends in mean BMI segregated by place of residence (a rural or urban area) from 1985 to 2017. We show that, contrary to the dominant paradigm, more than 55% of the global rise in mean BMI from 1985 to 2017-and more than 80% in some low- and middle-income regions-was due to increases in BMI in rural areas. This large contribution stems from the fact that, with the exception of women in sub-Saharan Africa, BMI is increasing at the same rate or faster in rural areas than in cities in low- and middle-income regions. These trends have in turn resulted in a closing-and in some countries reversal-of the gap in BMI between urban and rural areas in low- and middle-income countries, especially for women. In high-income and industrialized countries, we noted a persistently higher rural BMI, especially for women. There is an urgent need for an integrated approach to rural nutrition that enhances financial and physical access to healthy foods, to avoid replacing the rural undernutrition disadvantage in poor countries with a more general malnutrition disadvantage that entails excessive consumption of low-quality calories.

- Optimal growth and development in childhood and adolescence is crucial for lifelong health and well-being1–6. Here we used data from 2,325 population-based studies, with measurements of height and weight from 71 million participants, to report the height and body-mass index (BMI) of children and adolescents aged 5–19 years on the basis of rural and urban place of residence in 200 countries and territories from 1990 to 2020. In 1990, children and adolescents residing in cities were taller than their rural counterparts in all but a few high-income countries. By 2020, the urban height advantage became smaller in most countries, and in many high-income western countries it reversed into a small urban-based disadvantage. The exception was for boys in most countries in sub-Saharan Africa and in some countries in Oceania, south Asia and the region of central Asia, Middle East and north Africa. In these countries, successive cohorts of boys from rural places either did not gain height or possibly became shorter, and hence fell further behind their urban peers. The difference between the age-standardized mean BMI of children in urban and rural areas was <1.1 kg m–2 in the vast majority of countries. Within this small range, BMI increased slightly more in cities than in rural areas, except in south Asia, sub-Saharan Africa and some countries in central and eastern Europe. Our results show that in much of the world, the growth and developmental advantages of living in cities have diminished in the twenty-first century, whereas in much of sub-Saharan Africa they have amplified.

A century of trends in adult human height
- 2016
-
Ingår i: eLIFE. - 2050-084X. ; 5
-
Tidskriftsartikel (refereegranskat)abstract
- Being taller is associated with enhanced longevity, and higher education and earnings. We reanalysed 1472 population-based studies, with measurement of height on more than 18.6 million participants to estimate mean height for people born between 1896 and 1996 in 200 countries. The largest gain in adult height over the past century has occurred in South Korean women and Iranian men, who became 20.2 cm (95% credible interval 17.522.7) and 16.5 cm (13.319.7) taller, respectively. In contrast, there was little change in adult height in some sub-Saharan African countries and in South Asia over the century of analysis. The tallest people over these 100 years are men born in the Netherlands in the last quarter of 20th century, whose average heights surpassed 182.5 cm, and the shortest were women born in Guatemala in 1896 (140.3 cm; 135.8144.8). The height differential between the tallest and shortest populations was 19-20 cm a century ago, and has remained the same for women and increased for men a century later despite substantial changes in the ranking of countries.

Cost-Effectiveness of School-Based Prevention of Cannabis Use
- 2015
-
Ingår i: Applied Health Economics and Health Policy. - : Springer Science and Business Media LLC. - 1175-5652 .- 1179-1896. ; 13

Tidskriftsartikel (refereegranskat)abstract
- Background: Cannabis is the most frequently used illicit drug globally. Despite increasing evidence that cannabis use is associated with adverse health effects, the knowledge on preventative strategies is still limited. This study stemmed from a systematic review of effective prevention in which school-based programmes were identified as promising. The primary objective was to evaluate the cost effectiveness of Project ALERT (Adolescent, Learning, Experiences, Resistance, and Training), compared with ordinary ATOD (Alcohol, Tobacco, and Other Drug) education, among Swedish students in the eighth grade of compulsory school.Methods: The cost-effectiveness analysis was performed from the societal perspective with quality-adjusted lifeyears (QALYs) as an outcome (willingness-to-pay threshold €50,000) and follow-up periods from 1 year to a lifetime, considering a discounting rate of 3 %, and with costs inflated to 2013 levels. A Markov model was constructed on the basis of the ‘states’ of single use, regular use, daily use and use of other illicit drugs, which were associated with ‘complications’ of psychosis, schizophrenia, traffic accidents, depression and amotivational syndrome. Health and cost consequences were linked to both states and complications.Results: The programme was cost saving on the basis of evidence from the USA (ratio 1:1.1), and was cost effective (incremental cost-effectiveness ratio €22,384 per QALY) after reasonable adjustment for the Swedish context and with 20 years of follow-up. When the target group was restricted to boys who were neither studying nor working/doing work experience, the programme was cost effective after 9 years and cost saving (ratio 1:3.2) after 20 years.Conclusion: School-based prevention such as Project ALERT has the potential to be cost effective and to be cost saving if implemented in deprived areas. In the light of the shifting landscape regarding legalization of cannabis, it seems rational to continue the health economic analysis of prevention initiated here.

- Purpose This study seeks to investigate the long-term public health burden of Hodgkin lymphoma (HL) in terms of work loss following contemporary treatment protocols and associations with established treatment complications and lymphoma relapse. Methods We identified 1,989 Swedish HL patients (1,082 with clinical information) aged 18-60 (median 33) years at diagnosis 1992-2009, and matched 1:4 to population comparators. Sick leave, disability pension (work loss), and comorbidity were retrieved through September 2013. Relative risks (RR) with 95 % confidence intervals (CI) were calculated using Poisson regression, and mean lost work days were estimated yearly during follow-up. Results The risk of annual work loss was elevated in HL survivors versus comparators up to the 15th year post-diagnosis (RR5th year 1.64, 95 % CI 1.46-1.84; RR10th year 1.33, 95 % CI 1.15-1.34; and RR15th year 1.30, 95 % CI 1.04-1.62). The risk remained elevated up to the 10th year after adjustment for secondary malignancies and cardiovascular disease (RR10th year 1.31, 95 % CI 1.13-1.52). Advanced-stage patients had more lost days than comparators (mean number(5th year) 66 versus 33, mean difference 34, 95 % CI 20-48) as did patients receiving 6-8 chemotherapy courses (62 versus 33, mean difference(5th year) 30, 95 % CI 17-43). Among patients in the first complete remission, a difference was still observed for advanced-stage (51 versus 33, mean difference(5th year) 19, 95 % CI 5-34) but not early-stage disease. Conclusions Advanced-stage HL survivors treated with full-dose chemotherapy were at increased risk of work loss, not only explained by relapse, secondary malignancies, or cardiovascular disease.

BEST: Bypass equipoise sleeve trial; rationale and design of a randomized, registry-based, multicenter trial comparing Roux-en-Y gastric bypass with sleeve gastrectomy
- 2019
-

Tidskriftsartikel (refereegranskat)abstract
- Background: Laparoscopic gastric bypass (LGBP) is a well-documented surgical intervention for severe obesity. Recently, laparoscopic sleeve gastrectomy (LSG) has gained increased popularity. Short-term follow-up in limited-sized randomized trials comparing LGBP and LSG show no major differences in weight-loss, adverse events, or effect on comorbidities; however, there is a lack of sufficiently powered, pragmatic, randomized controlled trials comparing the mid- and long-term results of the two methods. Method: BEST is a randomized, registry-based, multicenter trial comparing LGBP and LSG. The trial has two primary outcomes; rates of substantial complications (SC) and total body weight loss. We hypothesize that patients treated with LSG will experience 35% fewer substantial complications during the 5-year follow-up compared to patients treated with LGBP, and that the efficacy of LSG will remain within a non-inferiority margin of 5% in terms of weight loss. Our sample size calculation, using data from the Scandinavian Obesity Surgery Registry (SOReg), shows a power of 80% for SC and > 95% for weight loss at p < .025 with a total of 2100 included patients. The design of the trial will also enable comparisons within several relevant patient subgroups. Conclusions: As a large-sized, pragmatic, randomized trial, BEST will provide robust data comparing LGBP with LSG by generating long-term results on weight loss and SC's, as well as secondary outcomes and comparisons within patient subgroups. The use of a well-established registry for registration of all data facilitates a large multicenter trial, and combines the strengths of registry studies with those of a randomized trial.

Prevalence of paediatric inflammatory bowel disease in Sweden : a nationwide population-based register study
- 2017
-
Ingår i: BMC Gastroenterology. - London, England : BioMed Central. - 1471-230X. ; 17
-
Tidskriftsartikel (refereegranskat)abstract
- Background: We evaluated the impact of different case definition algorithms on the prevalence of paediatric inflammatory bowel disease (IBD), Crohn's disease (CD) and ulcerative colitis (UC) and to compare the occurrence of certain diseases compared to matched controls.Methods: Paediatric patients (<18 years) were identified via ICD codes for UC and CD in Swedish registers between 1993 and 2010 (n = 1432). Prevalence was defined as >= 2 IBD-related visits. Prevalence of treated children in 2010 was defined as >= 2 IBD-related visits with one visit and >= 1 dispensed IBD-related drug prescription in 2010. To test the robustness of the estimates, prevalence was also calculated according to alternative case definitions. The presence of rheumatic, hepatobiliary, pancreatic, and dermatologic diseases were compared with age-/sex-/county-of-residence- matched general population controls.Results: The IBD prevalence was 75/100,000 (CD: 29/100,000; UC: 30/100,000; patients with IBD-U: 16/100,000). Prevalence of treated disease in 2010 was 62/100,000 (CD: 23/100,000; UC: 25/100,000; patients with IBD-U: 13/100,000). When age restrictions were employed, the prevalence estimate decreased (<17y: 61/100,000, <16y: 49/100,000 and <15y: 38/100,000).Compared to general population controls (n = 8583), children with IBD had a higher prevalence of dermatologic (4.7% vs. 0.6%), hepatobiliary (including primary sclerosing cholangitis) (5.5% vs. 0.1%), pancreatic (1.7% vs. 0%) and rheumatic diseases (7.2% vs. 1.2%; all P < 0.01).Conclusions: The overall prevalence of paediatric IBD in Sweden was similar to that in earlier regional cohorts. IBD patients had a higher prevalence of comorbid conditions than matched general population controls.

- Objective: To investigate in-depth speech results in the Scandcleft Trial 2 with comparisons between surgical protocols and centers and with benchmarks from peers without cleft palate. Design: A prospective randomized clinical trial. Setting: Two Swedish and one Finnish Cleft Palate center. Participants: One hundred twelve participants were 5-years-old born with unilateral cleft lip and palate randomized to either lip repair and soft palate closure at 4 months and hard palate closure at 12 months or lip repair at 3 to 4 months (Arm A), or a closure of both the soft and hard palate at 12 months (Arm C). Main Outcome Measures: A composite measure dichotomized into velopharyngeal competency (VPC) or velopharyngeal incompetency (VPI), overall assessment of velopharyngeal function (VPC-Rate), percentage of consonants correct (PCC score), and consonant errors. In addition, number of speech therapy visits, average hearing thresholds, and secondary surgeries were documented to assess burden of treatment. Results: Across the trial, 53.5% demonstrated VPC and 46.5% VPI with no significant differences between arms or centers. In total, 27% reached age-appropriate PCC scores with no statistically significant difference between the arms. The Finnish center had significantly higher PCC scores, the Swedish centers had higher percentages of oral consonant errors. Number of speech therapy visits was significantly higher in the Finnish center. Conclusion: At age 5, poor speech outcomes with some differences between participating centers were seen but could not be attributed to surgical protocol. As one center had very few participants, the results from that center should be interpreted with caution. © 2019, American Cleft Palate-Craniofacial Association.
