Low hand grip strength (HGS) is associated with the risk of cardiovascular diseases, but the association between HGS and myocardial infarction/angina pectoris (MIAP) is unclear. Furthermore, there have been no studies examining the associations of MIAP with anthropometric indices, absolute HGS indices, and relative HGS indices calculated by dividing absolute HGS values by body mass index (BMI), waist circumference (WC), waist-to-height ratio (WHtR), or weight values. Therefore, the objective of this study was to examine the associations of MIAP with absolute and relative HGS combined with several anthropometric indices.
In this large-scale cross-sectional study, a total of 12,963 subjects from the National Health and Nutrition Examination Survey were included. Odds ratios and 95% confidence intervals for the associations of MIAP with anthropometric indices, absolute HGS indices, and relative HGS indices were computed from binary logistic regression models. We built 3 models: a crude model, a model that was adjusted for age (Model 1), and a model that was adjusted for other relevant covariates (Model 2).
For men, the average age was 61.55 ± 0.16 years in the MIAP group and 66.49 ± 0.61 years in the non-MIAP group. For women, the average age was 61.99 ± 0.14 years in the MIAP group and 70.48 ± 0.61 years in the non-MIAP group. For both sexes, the MIAP group had lower diastolic blood pressure, shorter stature, greater WC, and a greater WHtR than did the non-MIAP group, and women tended to have greater systolic blood pressure, weight, and BMI than in men. HGS was strongly associated with the risk of MIAP in the Korean population. In men, relative HGS indices combined with WC and the WHtR had greater associations with MIAP than did the anthropometric indices and absolute HGS indices. However, in women, anthropometric indices, including weight, BMI, WC, and WHtR, were more strongly associated with MIAP than were absolute and relative HGS indices, unlike in men. When comparing absolute and relative HGS indices in women, relative HGS indices combined with BMI and weight was more strongly related to MIAP than was absolute HGS indices.
MIAP might be better identified by relative HGS than absolute HGS in both sexes. The overall magnitudes of the associations of MIAP with absolute and relative HGS are greater in men than in women.
低握力与心血管疾病风险相关，但握力与心肌梗死/心绞痛（MIAP）之间的关系尚不清楚。此外，尚无研究探讨 MIAP 与人体测量指数、绝对握力指数以及通过将绝对握力值除以体重指数（BMI）、腰围（WC）、腰高比（WHtR）或体重值计算得出的相对握力指数之间的关联。因此，本研究旨在探讨 MIAP 与绝对和相对握力与几种人体测量指数相结合的关联。
在这项大规模的横断面研究中，共纳入了来自全国健康和营养检查调查的 12963 名受试者。使用二元逻辑回归模型计算 MIAP 与人体测量指数、绝对握力指数和相对握力指数之间关联的比值比和 95%置信区间。我们构建了 3 个模型：一个未校正模型（模型 1）、一个校正年龄的模型（模型 2）和一个校正其他相关协变量的模型（模型 3）。
对于男性，MIAP 组的平均年龄为 61.55±0.16 岁，非 MIAP 组为 66.49±0.61 岁。对于女性，MIAP 组的平均年龄为 61.99±0.14 岁，非 MIAP 组为 70.48±0.61 岁。与非 MIAP 组相比，两性的 MIAP 组舒张压均较低，身高均较短，WC 均较大，WHtR 均较高，而女性的收缩压、体重和 BMI 均大于男性。握力与韩国人群 MIAP 的风险密切相关。在男性中，与人体测量指数和绝对握力指数相比，相对握力指数与 WC 和 WHtR 结合时与 MIAP 的关联更强。然而，在女性中，与绝对和相对握力指数相比，体重、BMI、WC 和 WHtR 等人体测量指数与 MIAP 的关联更强。在女性中，将绝对和相对握力指数进行比较时，与绝对握力指数相比，相对握力指数与 BMI 和体重相结合与 MIAP 的关系更为密切。
在两性中，相对握力可能比绝对握力更能识别 MIAP。MIAP 与绝对和相对握力之间的关联幅度在男性中均大于女性。
