ABSTRACT

OBJECTIVE: The incidence of work-related falls on the same level is increasing, particularly among middle-aged and older female workers. Vision is an important risk factor of falls. We investigated whether objectively measured visual acuity was associated with the incidence of falls. METHODS: This cohort study included 7,317 female employees aged 20-69 in Japanese supermarket stores. Monocular acuity measured during health checkups was classified into 3 levels ( ≥0.7, 0.3-0.7, <0.3). Incidence rate ratios (IRR) of work-related falls within one year were estimated. RESULTS: IRRs were 1.26 (95%CI: 0.92-1.72) in the 0.3-0.7 group and 2.27 (95%CI: 1.15-4.48) in the <0.3 group. CONCLUSIONS: Risk of work-related fall was higher in those with low visual acuity. Vision correction may contribute to fall prevention in workplaces.

ABSTRACT

OBJECTIVES: Despite evidence of breast cancer screening efficacy, the screening rate has remained less than 50% in Japan. This study aimed to evaluate the effect of an environmental approach offering on-site mammography in workplaces. METHODS: Supermarket stores were randomly assigned into two groups, the intervention group (leaflet and mammography) and the control group (leaflet). From May to July 2018, participants in the intervention group were given a leaflet informing them of the subsidies for breast cancer screening and offered the opportunity to have mammography in their workplaces. Participants in the control group were given the same leaflet, but had to arrange their own screening outside the workplace. The primary outcome was the breast cancer screening rate in 2018. The odds ratio (OR) and 95% confidence interval (CI) for having screening in the intervention group compared with the control group were estimated using multilevel logistic regression. RESULTS: We analyzed data from 1624 participants (mean age 53 years) from 25 supermarket stores (intervention: 8 stores, control: 17 stores). Among participants who had not attended screening in the previous year, the screening rate was 7% in the control group and 53% in the intervention group, with an adjusted OR (95% CI) of 14.22 (8.97-22.54). The effect was greater in those who had never attended screening before. CONCLUSION: In a worksite-based cluster randomized controlled trial in Japanese supermarket stores, an environmental approach offering mammography in workplaces substantially increased the breast cancer screening rate within 1 year (UMIN000030465).

ABSTRACT

OBJECTIVES: The current status of home blood pressure (HBP) measurement is unknown at a Japanese worksite. We aimed to calculate the proportion of individuals who periodically measured HBP and to explore the demographic and lifestyle characteristics of these workers. METHODS: The study included 4,664 employees aged 40-65 years who worked at a retail company and underwent health check-ups in 2018. Multivariable logistic regression models were used to estimate odds ratios (ORs) of participant's demographics and lifestyle characteristics and habits for HBP measurement by sex and medical treatment for hypertension. Periodic HBP measurement was defined as HBP measurements performed two times or more per month (opportunistic HBP measurement) among participants not being treated for hypertension, and daily measurement of HBP (everyday HBP measurement) among participants treated for hypertension. RESULTS: The percentages of opportunistic HBP measurement were 8.7% in males and 12.4% in females not being treated for hypertension. In both sexes, age (ORs per 1-year increment: 1.11 in males and 1.06 in females) and blood pressure (ORs of ≥ 140/90 mmHg: 7.42 in males and 4.71 in females compared with < 130/80 mmHg) were positively associated with opportunistic HBP measurement. Females treated for dyslipidemia (OR: 1.77), who had a self-described fast walking speed (OR: 1.49), and who exercised habitually (OR: 1.79) had significantly high ORs for opportunistic HBP measurement. Females who frequently consumed snacks after dinner had significantly lower ORs (0.65) than those who did not. The percentages of workers who did everyday HBP measurement were 21.6% in males and 25.5% in females treated for hypertension. Males treated for diabetes (OR: 0.23) had significantly lower OR than those who did not. Females treated for dyslipidemia (OR was 0.53), who had uncontrolled hypertension (OR: 0.58), consumed alcohol (OR: 0.60), and frequently ate within two hours before bed (OR: 0.54) had significantly lower ORs. Females who lived alone had significantly higher ORs (2.43) than those who did not. CONCLUSION: Approximately 10% of individuals not treated for hypertension periodically measured HBP. Age and blood pressure in males and females, and healthy lifestyles in females, were associated with having opportunistic HBP measurement. Approximately 25% of individuals treated for hypertension measured HBP every day. Individuals treated for dyslipidemia or diabetes and females with unhealthy lifestyle and uncontrolled hypertension were less likely to measure HBP every day.

ABSTRACT

Despite clear evidence of the benefits of lowering blood pressure among patients with hypertension, the treatment rate remains <40% worldwide. In the present trial, we aimed to investigate the effects of the early promotion of clinic visits among patients with untreated hypertension detected during annual health checkups. This was a worksite-based, parallel group, cluster-randomized trial with blinded outcome assessment. Employees of 152 Japanese supermarket stores found to have untreated hypertension (blood pressure levels ≥ 160/100 mmHg) during health checkups were assigned to an early promotion group (encouraged to visit a clinic in face-to-face interviews and provided with a referral letter to a physician as well as a leaflet) or a control group (received usual care), according to random assignment. The primary outcome was the completion of a clinic visit within 6 months. Odds ratios with 95% confidence intervals for the early promotion group versus the control group were estimated using multilevel logistic regression with random effects of clusters. A total of 273 participants (mean age 50.3 years, 55% women) from 107 stores were assigned to the early promotion group (138 from 55 stores) or control group (135 from 52 stores). During the 6-month follow-up, 47 (34.1%) participants in the early promotion group visited a clinic, as did 26 (19.3%) in the control group (odds ratio 2.33, 95% confidence interval 1.12-4.84, P = 0.024). Early promotion using a referral letter during health checkups significantly increased the number of clinic visits within 6 months completed by participants with untreated hypertension (UMIN000025411).

ABSTRACT

BACKGROUND: Despite a steady world-wide decline over recent decades, rates of smoking remain high in developed countries. In Japan, 30% of men and 10% of women are smokers. Based on these rates, 18.8 million (14.06 million men and 4.74 million women) in Japan are smokers. The rate of success for smoking cessation has recently improved due to the widespread availability of drug therapy; however, the success rate for quitting smoking one year after beginning therapy is only around 50%. Previous studies have demonstrated that exercise can relieve mental stress during continuous abstinence from smoking and curb smoking resumption. To date, no large-scale, randomized controlled trials have examined the effects of exercise on smoking cessation. The present study aims to determine the effects of exercise instruction on continuous abstinence from smoking after completion of smoking cessation therapy. METHODS: This is a multicenter, prospective, parallel-group, randomized controlled trial in Japan. We will enroll 300 individuals visiting a smoking cessation clinic (over 3 months) who have abstained from smoking in the second month after their initial visit as potential participants. Participants will not habitually exercise and will need to consent to participate. Participants will be randomly assigned to the exercise intervention group or control group. The intervention group will receive instruction on exercises that can be incorporated into their daily lives. The control group will be followed during the standard smoking cessation support program. The primary endpoint will be the continuous abstinence rate, and secondary endpoints will be weight, blood pressure, exhaled carbon monoxide concentration, psychological state, and blood test results. These indices will be compared between the intervention and control groups, with follow-up periods of 9 months in both groups. DISCUSSION: By examining the effects of exercise instruction after completion of 12-week smoking cessation therapy, this study should yield quality information that can be used to develop protocols to improve the continuous abstinence rate and inhibit weight gain after smoking cessation therapy.

ABSTRACT

The purpose of this study was to investigate the relationship between the frequency of outpatient visits and hypertension control as determined from health insurance records. This 9-year cohort study in Japan was based on 518 participants with hypertension who underwent health checkups in 2004. Participants were aged 35-56 years and none had a history of cardiovascular or cerebrovascular disease. All were covered by the same employee health insurer. Mean annual outpatient visit days at a hospital/clinic during the 9-year period were classified within four quartiles (Q1, Q2, Q3, Q4). Uncontrolled hypertension was defined as a systolic blood pressure (BP) ⩾140 mm Hg and a diastolic BP ⩾90 mm Hg. Logistic regression analysis was used to estimate the multivariable-adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for the prevalence of uncontrolled hypertension in groups Q1, Q2 and Q3 vs. Q4. The median (25th-75th percentile) annual outpatient visit days was 9.4 (4.0-15.5). Uncontrolled hypertension was observed in 62.4% of the participants in 2013. The multivariable-adjusted ORs and 95% CIs for uncontrolled hypertension in Q1, Q2 and Q3 vs. Q4 were 4.03 (2.28-7.12), 1.67 (0.99-2.81) and 1.44 (0.86-2.41), respectively. Uncontrolled hypertension increased significantly as the number of outpatient visits decreased (P for trend <0.001). This tendency was maintained when participants taking antihypertensive agents at baseline were excluded. Our study showed an inverse relationship between outpatient visit frequency and uncontrolled hypertension.

ABSTRACT

BACKGROUND: It is important that the general population be aware of the early symptoms, since it has been shown that early arrival to hospitals leads better prognosis of stroke patients. However, the general population is not well informed about the early symptoms of stroke. This study was conducted to clarify which stroke symptoms are less well known and which information sources are related to awareness of stroke symptoms. METHODS: A multiple-choice, mail-in survey involving 5,540 randomly selected residents, aged 40-74 years, of 3 cities in Japan was conducted. Their knowledge about stroke symptoms and their information sources were surveyed; information sources were classified as mass media (television/newspaper/radio) and personal communication sources (posters/leaflets/internet/health professionals/family and/or friends). 'Awareness' was defined as selecting all 5 of the correct stroke symptoms from among 10 listed symptoms with decoy choices. The estimated fraction of the possible impact due to each source on the whole population was also calculated by odds ratios (ORs) and the proportion of respondents who selected each source (Pe). The combined effects of mass media and personal communication sources on awareness were also assessed. RESULTS: Of the 5,540 residents, only 23% selected all 5 correct symptoms. Visual disturbance was the least known of the 5 symptoms (35%). All sources were positively related to awareness, with ORs (Pe) of: television, 1.58 (72.5%); newspaper, 1.79 (48.0%); radio, 1.74 (13.3%); posters, 1.73 (7.6%); leaflets, 1.50 (24.7%); Internet, 1.66 (5.6%); health professionals, 1.33 (34.8%), and family/friends, 1.21 (44.6%). The estimated fraction of the possible impact due to each source was higher for mass media (television, 0.31 and newspaper, 0.28) than personal communication sources (Internet, 0.04 and leaflets, 0.12). Mass media only and mass media/personal communication sources were significantly associated (ORs: 1.66, 2.75, respectively). CONCLUSIONS: As a single method of public education, television could be the most effective strategy. Moreover, the combined approach involving mass media and personal communication sources might have a synergistic effect. Less well-known symptoms, such as visual disturbances, should be noted in public education campaigns.
