The Relationship between Cold Hypersensitivity in the Hands and Feet and Health-Related Quality of Life in Koreans: A Nationwide Population Survey

الملخص EN

Aim.

We investigated the distribution of cold hypersensitivity in the hands and feet (CHHF) and examined the association between CHHF and health-related quality of life (HRQOL) among Koreans.

Methods.

Stratified multistage sampling was used for random selection of 2,201 adults.

HRQOL was assessed using the Short-Form 12-Item Health Survey (SF-12).

Cold hypersensitivity was measured using a new self-report questionnaire to score the extent of cold sensation in their hands, feet, and abdomen using a 7-point scale.

The correlation between CHHF and HRQOL was analysed using multiple regression analysis.

Results.

Cold hypersensitivity was present in the hands of 21.6%, the feet of 23.0%, and the abdomen in 22.5% of participants.

Cold hypersensitivity in the hands and feet was observed in 17.9%, at least one body part (hands, feet, or abdomen) in 34.2%, and all three body regions in 12.3% of participants.

The prevalence of cold hypersensitivity was significantly higher among women than among men, irrespective of the involved body part.

Cold hypersensitivity scores in the hands and feet correlated negatively with body mass index, but not with age.

The physical component summary (PCS) and mental component summary (MCS) of the SF-12 were both significantly lower in women with than in those without CHHF.

Among men, only the PCS was significantly lower in the CHHF group.

Multiple regression analysis, adjusted for sociodemographic variables, age, sex, and body mass index (BMI), confirmed that CHHF had negative effects on PCS and MCS.

Conclusions.

CHHF is more common in women and in individuals with a lower BMI.

CHHF has an independent negative effect on HRQOL.
