Obesity affects over 2.5 billion adults globally in 2022, posing a significant public health challenge. In Japan, obesity, defined as a body mass index ≥25 kg/m, impacted 33.0% of men and 22.3% of women in 2020. Despite this, over 25% of Japanese adults report no intention to improve health habits.The Health Interest Scale (HIS) assesses health-related attitudes across three dimensions: health consciousness, health motivation, and health value. Although overall HIS scores are associated with health outcomes, the specific roles of these dimensions in obesity risk are unclear. This study examines the associations between each HIS dimension and obesity risk among Japanese corporate employees, supporting targeted interventions for sedentary, working-age populations.
This cross-sectional study analyzed data from 2,260 employees of information technology-related companies in Japan, collected via health checkups and self-administered surveys in 2023. HIS scores (range: 0-36) were used as continuous variables. Logistic regression assessed associations between HIS subscale scores and obesity status, adjusting for demographic, occupational, and lifestyle factors and obesity-related diseases.
Higher scores on each HIS dimension were associated with lower obesity odds. Adjusted odds ratios per one-point increase were: health consciousness, 0.84 (95% confidence interval: 0.81-0.88); health value, 0.85 (0.81-0.89); and health motivation, 0.91 (0.87-0.95). Male sex, short sleep (<7 hours), and sedentary occupations were associated with increased obesity odds (all p < 0.001). The associations remained significant after adjustment for obesity-related diseases. Additionally, stronger associations were observed among participants with obesity-related diseases in univariate analysis.
This study identified significant associations between the three HIS dimensions and obesity risk, which remained robust after adjusting for obesity-related diseases. Stronger associations were observed across all HIS dimensions in participants with obesity-related diseases. These findings underscore the importance of tailored interventions targeting HIS dimensions, particularly health consciousness and health value, to reduce obesity risk in sedentary, working-age populations.
2022年，全球超过25亿成年人受肥胖影响，这构成了重大的公共卫生挑战。在日本，2020年，体重指数≥25千克/平方米被定义为肥胖，有33.0%的男性和22.3%的女性受其影响。尽管如此，超过25%的日本成年人表示无意改善健康习惯。健康兴趣量表（HIS）从健康意识、健康动机和健康价值三个维度评估与健康相关的态度。虽然HIS总分与健康结果相关，但这些维度在肥胖风险中的具体作用尚不清楚。本研究调查了日本企业员工中HIS各维度与肥胖风险之间的关联，为久坐不动的工作年龄人群提供有针对性的干预措施提供支持。
这项横断面研究分析了2023年通过健康检查和自我管理调查收集的日本信息技术相关公司2260名员工的数据。HIS得分（范围：0 - 36）用作连续变量。逻辑回归评估HIS子量表得分与肥胖状况之间的关联，并对人口统计学、职业和生活方式因素以及肥胖相关疾病进行调整。
HIS各维度得分越高，肥胖几率越低。每增加一分的调整优势比为：健康意识，0.84（95%置信区间：0.81 - 0.88）；健康价值，0.85（0.81 - 0.89）；健康动机，0.91（0.87 - 0.95）。男性、睡眠不足（<7小时）和久坐职业与肥胖几率增加相关（所有p<0.001）。在对肥胖相关疾病进行调整后，这些关联仍然显著。此外，在单变量分析中，肥胖相关疾病患者之间的关联更强。
本研究确定了HIS三个维度与肥胖风险之间的显著关联，在对肥胖相关疾病进行调整后，这种关联仍然很显著。在患有肥胖相关疾病的参与者中，所有HIS维度的关联更强。这些发现强调了针对HIS维度，特别是健康意识和健康价值进行量身定制的干预措施对于降低久坐不动的工作年龄人群肥胖风险的重要性。
