National data showed an increased prevalence of overweight and obesity among four-year-old Swedish children during the first year of COVID-19.

AIM: This paper summarised national data on the prevalence of overweight and obesity among 4-year-old children in Sweden in 2020, the first year of the COVID-19 pandemic. It compares this with data from 2018. Differences between regions and sex were identified. METHODS: Comparative data from Swedish Child Health Services were available for 18/21 regions. Chi-square tests were used to compare data from 2018 and 2020 and to examine differences between the sexes. Sex and year were examined through interaction tests. RESULTS: In 2020, 13.3% of the 100 001 children had overweight or obesity: 15.1% of the girls and 11.6% of the boys (p < 0.001). In 2018, 11.4% of the 105 445 children had overweight or obesity: 13.2% of the girls and 9.4% of the boys. This was an overall increase of 16.6% (p = 0.000) in the national Swedish data from 2018 to 2020. The increase between the years was greater for obesity (31.8%, p = 0.000) than for overweight (13.3%, p = 0.000). CONCLUSION: The prevalence of overweight and obesity among 4-year-olds in Sweden increased during the COVID-19 pandemic and needs to be addressed. The prevalence needs to be followed as part of prevention programmes and to evaluate health interventions

Incidence of tonsillar cancer in northern Sweden : Impact of human papilloma virus

The incidence rate of tonsillar cancer is increasing worldwide. The current study identifies a parallel increase in the incidence of tonsillar cancer, human papilloma virus (HPV) and p16 expression among a population from northern Sweden, a sparsely populated area, confirming the strong association between p16 and HPV infection in tonsillar tissue. Data from the Swedish Cancer Registry was assessed to identify cases of tonsillar cancer in the northern territorial area of Sweden. HPV DNA was extracted from paraffin embedded diagnostic biopsies and detected by polymerase chain reaction using general primers Gp5+/6+ and CpI/IIG. Expression of p16 was identified by immunochemistry. Patients were grouped into urban or rural residence categories. A total of 214 cases were identified, comprising 155 (72.4%) men and 59 (27.6%) women, and 65 of these patients, who presented between 2000 and 2012, were analyzed. The overall median age for the analyzed patients was 58 years; 48 (74%) were males (median age, 57.5 years) and 17 (26%) were females (median age, 65 years). Of the 65 specimens, 59 (91%) were positive for HPV, and 62 (95%) expressed p16. The incidence of tonsillar cancer in the cohort demonstrated a 2-fold increase between 1990 and 2013; specifically, a 2.7-fold increase was observed in men whilst the female group exhibited only a small increase. These findings demonstrate a strong association between p16 expression and HPV infection in tonsillar malignancies. The incidence of HPV-positive tonsillar cancer has increased in recent years, even in sparsely populated regions, as demonstrated in northern Sweden
