Mental Health and Lifestyle Survey

Outline of the Mental Health and Lifestyle Survey

Purpose

Since the Great East Japan Earthquake and the accident at TEPCO’s Fukushima Daiichi NPS, many people in Fukushima Prefecture feel anxious and stressed by the experience and evacuation. The Mental Health and Lifestyle Survey was launched with the aim of comprehending the physical and mental health and lifestyle of the residents, so we can provide each of them with individualized medical care, health care, and welfare services.

Eligible Persons

  • Those who were registered as residents in the covered area* from March 11, 2011 to April 1, 2012 (even after moving out of the area)
  • Those who are registered as residents in the officially designated evacuation zone as of April 1 of each year of the CHC
  • Other than those above, as necessary, based on Basic Survey results.

* Covered area: 13 municipalities designated by the national government as evacuation zones in 2011
Hirono Town, Naraha Town, Tomioka Town, Kawauchi Village, Okuma Town, Futaba Town, Namie Town, Katsurao Village, Iitate Village, Minamisoma City, Tamura City, Kawamata Town, and parts of Date City (specific spots recommended for evacuation)

Implementation Status

FY2023 Survey (As of October 31, 2024)

  • Eligible Population: 190,748
    Children (Ages 15 and younger): 16,601
    Adults (Ages 16 and older): 174,147
  • Number of responses (Response rate): 33,033 (17.3%)
    Children (Ages 15 and younger): 1,661 (10.0%)
    Adults (Ages 16 and older): 31,372 (18.0%)

Yearly changes of the survey results

Changes in the percentage of children with an SDQ score (emotional and behavioral assessment) of 16* points or more

  • The proportion of high-risk children with emotional or behavioral problems was high across all age groups in FY2011, with particularly elevated levels among those aged 4 to 6 years (24.4%). Since then, the proportion has decreased across all age groups and has improved to nearly that reported in the previous study (9.5%).

* SDQ (Strengths and Difficulties Questionnaire) criteria with a cutoff value of 16 points based on previous studies

Changes in the percentage of those scoring 13* points or higher on K6

  • In FY2011, 14.6% of individuals were considered to be in need of support due to the possible presence of mood disorders such as depression or anxiety disorders. This proportion has shown an improving trend, reaching 5.4% in FY2023. However, it remains higher than the proportion reported in a previous study of the general population not affected by the disaster (3%). Continued careful support and monitoring are therefore considered necessary.

* K6 Distress Scale criteria with a cutoff value of 13 points, based on previous studies

Changes in the frequency of exercise in adults

  • The exercise frequency of “Almost every day” and “2-4 times a week” improved gradually, reaching 43.9% in the FY2023 survey. A national survey showed 44.8% for those who exercise more than 2 days a week (20 old and older), although not directly comparable with our survey because of differences in participants’ age and other attributes, indicating that the exercise habits of Fukushima residents were similar to those in Japan overall.

Changes in the percentage of problematic drinking (CAGE score of 2 points or higher)

  • In FY2023, the proportion of participants at high risk for problematic drinking was 13.9% among males and 6.5% among females, with both showing a decreasing trend.

Influences on daily life due to the spread of COVID-19

  • In the FY2023 survey, those who responded that COVID-19 exerted influence on their daily life "Significantly" or "To some extent" accounted for 26.5%, which decreased compared to FY2022.

* Percentages have been rounded and may not total to 100%.

Changes in the proportion of risk perception of radiation effects to the next generation

  • Regarding possible radiation effects on the next generation, 19.7% responded that they think effects on the next generation are likely to occur (“Possibilities are high” and “Possibilities are very high” combined) in the FY2023 survey. These percentages have been gradually decreasing.

Provision of support to those in need

FY2023 Survey (Numbers confirmed on December 31, 2024)

Among the survey respondents, those who were assessed as needing consultation or support based on their mental health status and lifestyle habits were provided with telephone support. Through these calls, their situations were assessed, and advice for improvement, as well as recommendations to seek care at health or medical institutions, were provided.

Number of support candidates and recipients for issues regarding children

Number of support candidates and recipients for issues regarding adults

* For those who met Criteria I, our “Mental Health Support Team” of clinical psychologists, public health nurses, clinical nurses, etc., made phone calls and provided counseling. The team asked about support recipients' health conditions, assessed current problems, and advised further examination at health/medical facilities when necessary.

* For those who met Criteria II, we sent reply-paid postcards to confirm their intention regarding telephone counseling. Telephone counseling was provided to those who expressed an intention to receive support or were judged to need support based on the content of their replies.
