RESUMO

BACKGROUND: As at June 14, 2023, the coronavirus disease 2019 (COVID-19) pandemic had affected more than 767 million people and caused more than 6.9 million deaths worldwide. This study aimed to clarify the lifestyle factors that influence the exacerbation of COVID-19 severity. METHODS: This was a cross-sectional study of patients with COVID-19 whose severity classification of "moderate or severe" (COVID-19 exacerbation) was defined as an objective variable. The 1,353 participants were selected from 4,899 patients with COVID-19 between August 10, 2020 and December 10, 2022. Participants who underwent a specific health checkup before the date for a COVID-19 consultation were included. Using binominal logistic regression analysis, we evaluated the odds ratios (ORs) for COVID-19 exacerbation according to lifestyle-related factors. Limitations were discussed using a target trial emulation framework which clarifies problems in observational studies. RESULTS: The explanatory variables extracted as factors that exacerbated COVID-19 severity were gender (OR [man vs. woman]: 2.533, 95% confidence interval [CI] 1.484-4.322); age (OR [50s vs. 10s, 20s, or 30s]: 4.858, 95% CI 2.319-10.177; OR [60s]: 9.738, 95% CI 4.355-21.777; OR [70s + 80s + 90s]: 8.327, 95% CI 3.224-21.507); and comorbid chronic lung disease (OR ['yes' vs. 'no']: 2.892, 95% CI 1.227-6.818). The explanatory variables extracted as factors that reduce the severity of COVID-19 were hospital consultation year (OR [2022, predominantly Omicron variant prevalent vs. 2020, predominantly Alpha variant prevalent]: 0.180, 95% CI 0.058-0.559); number of vaccinations (OR [2 doses vs. 0 or one doses]: 0.223, 95% CI 0.114-0.436; OR [≥3 doses vs. 0 or one doses]: 0.090, 95% CI 0.035-0.229); regular exercise (exercising ≥2 days/week ≥30 minutes each at an intensity that causes a slight sweat for ≥1 year) (OR ['yes' vs. 'no']: 0.458, 95% CI 0.242-0.866). CONCLUSIONS: These results suggest the importance of vaccination, regular exercise, and prevention of chronic lung disease as measures against exacerbation of COVID-19 severity.

RESUMO

In Japan, specific health checkups were implemented to prevent metabolic syndrome (MetS) and cardiovascular diseases in April 2008. This study aimed to clarify the relationship between lifestyle factors and the MetS incidence to understand how the disease can be prevented and to improve the public health policy. A retrospective cohort study was conducted using the specific health checkup data of 2,781 workers. Lifestyle factors were assessed using lifestyle-related items in the general health questionnaire included in the specific health checkups. The hazard ratio values for the incidence of MetS according to lifestyle-related items were determined from the data of the specific health checkup for 12 years. The Cox proportional hazard survival model was used to evaluate hazard ratio values after adjusting for confounding factors. The limitations of this research method are discussed using a target trial emulation framework which investigates problems such as biases in observational studies. The crude incidence rates per 1,000 person-years of MetS in women and men were 15.25 and 47.58, respectively. Three dietary lifestyle-related factors, namely "Eating snacks and sweet beverages other than breakfast, lunch, and dinner," "Eating faster than others," and "Skipping breakfast at least three times a week," were identified, with the hazard ratio values 1.262 (95 % confidence interval [CI] 1.032-1.542, p = 0.023), 1.220 (95 % CI 1.032-1.442, p = 0.020) and 1.189 (95 % CI 1.012-1.397, p = 0.036), respectively. These results suggest that lifestyle improvements related to extracted lifestyle-related items contribute to the prevention of MetS.

RESUMO

The incidence of gastric cancer in Okinawa Prefecture is the lowest in Japan, which is attributed to differences in strains of Helicobacter pylori in Okinawa and other prefectures in Japan. Our aim was to compare the endoscopic findings of H. pylori-infected gastric mucosa in Okinawa and Tokyo. Patients who underwent upper gastrointestinal endoscopy (UGI) at Northern Okinawa Medical Center (Okinawa group) and Juntendo University Hospital (Tokyo group) from April 2019 to March 2020 were included. Patients diagnosed with H. pylori-infected gastric mucosa were retrospectively compared between the Okinawa and Tokyo groups according to the Kyoto Classification of Gastritis. The numbers of subjects (Okinawa/Tokyo) were 435/352, male/female ratio was 247:188/181:171, and age was 53.3 ± 14.7/64.6 ± 14.3 (mean ± standard deviation) years. Regarding the Kyoto Classification of Gastritis, the prevalence (Okinawa/Tokyo) of the closed type of atrophic gastritis was 73%/37% (p < 0.001), diffuse redness 80%/84% (p = 0.145), mucosal swelling 46%/46% (p = 0.991), enlarged fold 26%/32% (p = 0.048), spotty redness 77%/68% (p = 0.002), sticky mucus 17%/36% (p < 0.001), and intestinal metaplasia 32%/42% (p < 0.001). Age analysis also revealed that closed-type atrophy and spotty redness were more frequent in the Okinawa group than in the Tokyo group. There may be regional differences in endoscopic findings of H. pylori-infected gastric mucosa between Okinawa and Tokyo.
