Objective: The purpose of this study was to create a radar chart that visually summarizes 12 items related to the blood pressure (BP) and blood metabolism as a tool to support the health guidance for primary prevention in post-health checkup measures. The chart, called the Metabolic Chart (MC), was designed with the 12 basic items related to metabolism arranged on a clock face.

Methods: The study was conducted between April 2021 and March 2022, with 7,622 participants (4,079 males, 3,543 females) aged 20 to 59 who underwent health checkups. The study used the MC to show the average values of the groups classified by obesity and drinking habits.

Results: The results showed that in the MC of the three obese groups, except for HDL-C and Hb, males’ values for the other items deteriorated gradually with increasing obesity. In the females, deterioration was observed in ALT, LDL-C, and HbA1c in obesity level 2 or higher. The analysis of variance between the three groups showed that all items were significant (p<0.01) in each group for both males and females. In the MC of the two groups with different drinking amounts and frequencies, the males showed deterioration in AST, ALT, γ-GTP, TG, and BP in the heavy-drinking group, while the females showed no differences in any item. The t-test between the two groups showed that in males, the AST, γ-GTP, HDL-C, TG, HbA1c, UA, and BP were significant (p<0.01), while there were no significant differences in the other five items. In the females, the AST, γ-GTP, HDL-C, LDL-C, TG, FBG, HbA1c, UA, and BP were significant (p<0.01), while there were no significant differences in the other three items.

Conclusions: The MC is expected to be used not only as a tool to assist health guidance, but also as a trigger for behavioral change in the participants.

Objective: We report the preliminary results of vitamin D screening using serum 25(OH)D measurements in our health screening center.

Methods: We evaluated serum 25(OH)D in 87 people (70 women, 17 men) from October 2020 to May 2022. We evaluated whether serum 25(OH)D is associated with basic characteristics including age, gender, %YAM, BMI, and eGFR.

Results: Their average age was 59±10 years. Levels of serum 25(OH)D were divided into 4 groups. The Normal group (≧30ng/mL) was 6 (6.9%), the Suboptimal group (≧20ng/dL, <30ng/dL) was 15 (17.2%), the Deficiency Group (≧10ng/dL, <20ng/dL) was 50 (57.5%), and the Severe Deficiency Group (<10ng/dL) was 16 (18.4%). Seventy-six people evaluated %YAM simultaneously. Twelve people were less than 80%. Serum 25(OH)D tends to be low in younger people (r=0.19, p=0.08), in particular significant in males (r=0.51, p=0.04). And serum 25(OH)D was not associated with gender, %YAM, BMI and eGFR.

Conclusion: Less than 10% of people had normal levels of serum 25(OH)D and approximately 80% of people had deficient levels. We might need to recognize that vitamin D deficiency is not rare in health screening centers. Because serum 25(OH)D tends to be low in younger people, screening of vitamin D deficiency would be necessary in younger people.

  Early diagnosis and treatment are critical for chronic kidney disease. We provided lifestyle counseling, nutritional education, and individual exercise guidance by health fitness programmers to examinees with early chronic kidney disease associated with lifestyle-related diseases detected in our facility’s health checkups. Between November 2020 and August 2021, 48 examinees with early chronic kidney disease (mean age 64.9 ± 7.8 years, 21 men, 27 women, and mean estimated glomerular filtration rate 55.8 ± 6.8 mL/min/1.73 m²) received individual exercise guidance including stretching and resistance training. Of the 48 examinees, 25 examinees (52%) did not exercise frequently, and 4 examinees (8%) who had been doing exercises that overloaded the joints were instructed to exercise appropriately. Exercise guidance, as with nutritional education, should be tailored to the background and lifestyle of each examinee. In examinees with early chronic kidney disease, individual exercise guidance by health fitness programmers may have significance as an opportunity to initiate exercise or to review exercise methods.
