  By the way, although childhood obesity has recently become a problem, it is said that 80% or more of childhood obesity shifts to obesity after adulthood. This is because the fat cells increased in childhood are enlarged after becoming an adult. And since it is said that fat cells do not proliferate after adulthood, in order to prevent obesity in adults, it is important to live a life without becoming obese since childhood. However, it is said that recent children are no longer playing outside due to the spread of urban life and home game machines. Also, walking distance to school is short in urban areas, while in rural areas, the chances of walking are extreme because they are picked up by cars due to the increase in cars, suspicious people, and the appearance of bears in satoyama due to natural destruction Has decreased.

  Because of these, the amount of daily activities of children decreases, which increases childhood obesity and is a social problem. Therefore, in order to prevent childhood obesity, it is important to understand the amount of activity in the daily life of the child and provide guidance to increase exercise opportunities, but the purpose is to manage the amount of activity provided in the past The device to be used is a general-purpose device such as the momentum measurement management device disclosed in Patent Document 1, and cannot be managed for childhood obesity.

FIG. It is a figure which shows the relationship between the sleep time relevant to Embodiment 4, and the secretion of growth hormone. It is an actual measurement example figure which shows the relationship between the sleep state in Embodiment 4, and an acceleration value.

  Embodiments of the present invention will be described below.

(Embodiment 1)
As shown in FIG. 1, the activity meter of the present embodiment includes an acceleration sensor 1 as a body motion detecting unit that detects the body motion of the measurement subject, a computation unit 2 that performs various computation processes described later, and a computation. Standard activity data storage unit 3 as a storage means for storing standard activity data to be used, data storage unit 4 used for temporary storage of data, and input operation unit for inputting height and weight data of the person to be measured 5, a display unit 6, and a battery power source (not shown), and is built in a small casing (not shown) so that the display surface of the display unit 6 is exposed. The acceleration due to the body movement of the person to be measured is obtained as body movement data by the built-in acceleration sensor 1.

  The calculation unit 2 takes in the detection output of the acceleration sensor 1 and counts the peak value of the detected acceleration, thereby calculating the number of steps per minute (Pe), the number of steps (Pe), and an input operation in advance. Energy consumption per minute (1) from the height ([St [m]) and weight (W [kg]) of the measurement subject input from the unit 5 and stored in the data storage unit 4 ( Ce), that is, a function as motion calculation means for calculating exercise intensity.

Ce = St × 0.4 × Pe × W / 2/1000 (1)
Instead of obtaining the number of steps (Pe), an operation for converting the activity amount (Me) from the relationship between the average acceleration fluctuation value and the activity amount shown in FIG. 2 is performed, and this activity amount (Me) data is input. A calculation function for obtaining energy consumption (Ce) per minute from the measured body weight (W [kg]) of the measurement subject may be provided as in equation (2). Note that the approximate curve (I) in FIG. 2 indicates that the ratio R between the fluctuation value of the acceleration and the amount of activity is 0.92.

Ce = Me × W / 60 (2)
Is required.

  The calculation unit 2 further obtains the daily energy consumption from this energy consumption value, and Table 1 shows the daily energy consumption and a part of the standard activity data stored in the standard activity data storage unit 3. Compared with the daily energy consumption corresponding to each gender age group shown, living activity level I to IV (exercise level) is determined, but in the growth period, weight gain due to growth must be considered Therefore, in the present embodiment, the computing unit 2 stores the basal metabolism (kcal / kg / day) based on the age group and body weight stored in the standard activity data storage unit 3 as standard activity data (see Table 2). And an amount of energy <see Table 3> corresponding to a standard ratio of weight that increases daily is calculated.

  For example, in the case of a boy who is 9 years old and has a weight of Wkg, the base energy amount (Be) is obtained as shown in equation (3).

  Be = 37.4 × W + 34 (3)

  Further, the calculation unit 2 takes the ratio (R) between this value and the consumed energy Ce recorded by wearing the activity meter of the present embodiment as shown in the equation (4), and the ratio (exercise intensity) is shown in Table 1. The exercise level is determined by comparing with the value of “r” of the daily activity intensity shown in FIG. 6 and the exercise level is displayed on the display unit 6. That is, the calculation unit 2 has a function as an exercise level calculation means.

R = Ce / Be (4)
In order to determine the exercise level, each value in the table is defined as a median range.

  For example, in a 9-year-old boy, when the exercise level (life activity level) is determined to be II, it is assumed that the range is 1.4 <R ≦ 1.6 or Ce ≦ 2150.

  In this way, the measurement subject and his / her family can perform health management of the measurement subject in the growth period based on the exercise level that takes into account the characteristics of the growth period.

(Embodiment 2)
In the first embodiment described above, the exercise level is obtained. However, in this embodiment, in addition to the exercise level, the bone density of the measurement subject is also measured, and safety management is performed to prevent a fracture or the like from occurring. Can also be performed.

  That is, in this embodiment, as shown in FIGS. 3 (a) and 3 (b), the bone density based on the change in the bone density of the lumbar spine during the growth period and the change in the amount of activity per day and the bone density shown in FIG. It is an example which showed. (Figs. 3 and 4 are the 1996 Ministry of Health and Welfare Research on Mental and Physical Disorders. Study on the Influence of Living Environment on Children's Health "Examination of Bone Density and Activity Levels in School Girls." (See research results by Aki et al.)

  In view of these points, in order to automatically measure and display the bone density in the growth period, in the present embodiment, the approximate activity data shown in FIG. 4 is stored in the standard activity data storage unit 3 as the standard activity data. Bone that is stored together with data and estimates whether or not the operation unit 2 can improve the bone density by applying the value calculated by the above formula (1) or (2) to the approximate curve. It is characterized in that the calculation unit 2 has a function as density estimation means.

  In this case, if a curve of the activity amount and the bone density increase amount for each age is displayed on the display unit 6 in a form added to the graph of FIG. 3, optimal exercise for maintaining the bone density is performed for each age and sex. It can be shown to the person to be measured (or the family).

  This display may be performed by switching to the exercise level display, or may be displayed simultaneously. Other configurations are the same as those of the first embodiment, and thus description thereof is omitted.

  The activity meter according to the present embodiment includes a body motion detection unit that detects body motion of a measurement subject, a motion calculation unit that calculates exercise intensity from body motion data detected by the body motion detection unit, and human growth. Storage means for storing standard energy consumption obtained in advance for each age group corresponding to a period. The activity meter calculates the exercise level of the measurement subject by comparing the exercise intensity calculated by the exercise calculation means with the energy consumption corresponding to the age group of the measurement subject read from the storage means. Means and another storage means for storing the relationship between exercise intensity and bone density or the relationship between acceleration and bone density. Furthermore, this activity meter is the relationship between the exercise intensity calculated by the exercise calculation means or the acceleration obtained from the body movement data of the body movement detection means, and the exercise intensity and bone density stored in another storage means, Alternatively, a bone density estimating means for estimating the bone density of the measurement subject from the relationship between acceleration and bone density is provided. As a result, the bone density of the person being measured can be known, and as a result, management such as increasing the number of exercise opportunities to obtain the required bone density as a growth period can be performed, and fractures due to insufficient bone density can occur. Safety management to prevent it is possible.

(Embodiment 3)
In the present embodiment, an illuminance detection means 8 such as CdS is further added to the configuration of FIG. 1 as shown in FIG. 5, and the illuminance detected by the illuminance sensor 7 as the illuminance detection means is higher than a certain illuminance. If there is, it is determined that it is active under sunlight, not under artificial lighting, and has a function as an outdoor activity time measuring means for measuring the outdoor activity time, and the outdoor activity time is accumulated to store data. The unit 4 has a function to display the outdoor activity time which has received sunlight on the display unit 6 while displaying the outdoor activity time so that the user can be encouraged to go out. It is.

  Here, exposure to sunlight leads to the production of vitamin D, which is closely related to the above-mentioned bone density, and during the growth period, exposure to sunlight for 30 minutes to 1 hour is required as a necessary amount per day. . Therefore, the above-mentioned display prompts the person to be measured to go out. Moreover, the outdoor activity time corresponding to the quantity which received sunlight is used as one of the parameters at the time of bone density estimation of Embodiment 2. In this case, the linear parameter with the best value of 1 hour or more is used.

The present embodiment is used by being worn on the body of the person being measured while sleeping, as a sleep amount calculating means for determining whether to turn over or awake from the acceleration detected by the acceleration sensor 1 and calculating sleep time. The function is given to the calculation unit 2.

  Here, since acceleration in mid-wake awakening occurs more continuously than acceleration due to turning over, etc., the computing unit 2 calculates the sleeping time by determining the mid-wake awakening or turning over, and from the relationship between sleep time and daytime exercise intensity. The relationship between the sleep time and the daytime exercise intensity can be displayed to the measurement subject through the display unit 6 such as determining that the sleep time is short due to lack of daytime activity. The display means can show the relationship between sleep time and lack of exercise to the person to be measured and family, and can serve as a guideline for strengthening the amount of activity so as to obtain sufficient sleep time.

  If the sleep time is short and it is determined that sleep is not good, it is estimated that the amount of activity during the day is low or that there is intense exercise before going to bed. Instructing proper exercise (about 30 minutes of aerobic exercise a few hours before going to bed).

In addition, FIG. 6 is data showing the relationship between the completed time and growth hormone. As can be seen from this data, since the secretion of growth hormone increases as the sleep time increases, the sleep time of the child who is the subject of measurement should be managed. Therefore, it is possible to manage life by taking enough sleep so that the secretion of growth hormone is not insufficient.
