Sweden's obesity crisis deepens: rates have doubled in four decades
A new analysis of Northern Sweden reveals obesity has doubled since 1986, now affecting over one in four adults. The trend signals mounting pressure on healthcare systems and workforce productivity across Europe, with serious implications for employers, insurers, and public health budgets.
Originaltitel: Long-Term Obesity Trends in Northern Sweden: Cross-Sectional Data From the MONICA Study (1986-2022).
Obesitas i Norrland har fördubblas sedan 1986 — en utveckling som direkt påverkar regionvårdens kapacitet och investeringsbehov inom metabola sjukdomstillstånd. Data från åtta populationsbaserade undersökningar mellan 1986 och 2022 inom MONICA-studien visar att fetma ökat med 15,7 procentenheter bland män och 12,1 procentenheter bland kvinnor. År 2022 hade 26,6 procent av männen och 26,3 procent av kvinnorna diagnosen fetma. Bukfetma har växt ännu kraftigare: män med midjemått ≥102 cm ökade med 21,5 procentenheter. Forskargruppen vid Luleå och Umeå universitet analyserade 12 950 deltagare med genomsnittlig svarsfrekvens på 68,2 procent. Resultaten signalerar omedelbar behov av strukturerade interventionsprogram i primärvården. För inköpschefer inom regionvård och MedTech-aktörer underlättar trenden planering av diabetesdiagnostik, övervakningsutrustning och nutritionssamordning de närmaste åren.
BACKGROUND: Elevated BMI and central adiposity increase the risk of cardiovascular disease, type 2 diabetes, and several cancers. Obesity has risen in recent decades, with Northern Sweden exceeding the national average. Anthropometric trends in the Northern Sweden MONICA study have not been updated since 2004. OBJECTIVE: To describe overweight and obesity trends in Northern Sweden from 1986 to 2022. METHODS: Eight population-based surveys were conducted between 1986 and 2022 within the Northern Sweden MONICA study. In each survey, 2000-2500 adults aged 25-74 years were invited; 12,950 participated (mean age 49.5 [SD 13.6]; 51% women), with a 68.2% response rate. Anthropometry was assessed using standardized protocols. RESULTS: Obesity increased by 15.7 percentage points in men and 12.1 percentage points in women. By 2022, obesity had doubled since 1986, reaching 26.6% in men and 26.3% in women. Abdominal obesity also increased: with waist circumference ≥ 102 cm in men and ≥ 88 cm in women rising by 21.5 and 4.9 percentage points, respectively. CONCLUSIONS: General and abdominal obesity have substantially increased in Northern Sweden over the past four decades. These findings call for urgent, coordinated, and multi-level interventions, as continued increases in obesity pose serious long-term risks to population health and healthcare sustainability.
