    Although many studies have shown the relationships between oral function and nutrition and health, few reports have investigated the masticatory behaviors of older people. This study aimed to clarify the relationships between oral function and the masticatory behaviors and features of masticatory behaviors with oral hypofunction. A total of 98 community-dwelling independent older adults participated. Seven oral conditions related to oral hypofunction were examined, and the masticatory behaviors when consuming a rice ball were measured. The participants were divided into two groups according to the criteria for oral hypofunction, and the masticatory behaviors were compared. Furthermore, the relationship between masticatory performance and the number of chews was investigated. The chewing rate of the oral hypofunction group was slower than that of the no oral hypofunction group, but there was no difference in the number of chews and chewing time. The decreased tongue-lip motor function group showed a slower chewing rate, and the decreased tongue pressure group showed a smaller number of chews and shorter chewing time. No significant correlation was observed between masticatory performance and behavior. In conclusion, older adults with oral hypofunction chewed slowly due to decreased dexterity, while, even if oral and masticatory function decreased, no compensatory increase in the number of chews was observed.

    Because a relationship has been reported between masticatory behavior, obesity, and postprandial blood glucose, it is recommended to chew well and take a longer time to eat. The purpose of this study was to examine the possibility of changing masticatory behavior using a small ear-hung wearable chewing counter, which can monitor masticatory behavior without disturbing daily meals. In total, 235 healthy volunteers participated in a 4-wk randomized controlled trial and were divided into 3 groups. All participants were instructed about the importance of mastication at the first visit. During the intervention, group B used the chewing counter without an algorithm during each meal (notification of the number of chews after meal), and group C used the chewing counter with a masticatory behavior change algorithm (setting a target value and displaying the number of chews in real time). Group A was set as the control group. The number of chews and the meal time when consuming 1 rice ball (100 g) were measured before and after the intervention using the chewing counter, and the rate of change in these values was evaluated. Participants also provided a subjective evaluation of their changes in masticatory behavior. The number of chews and the meal time of 1 rice ball increased significantly in groups B and C compared with before the intervention, and the rate of change was significantly higher in group C than in group A and group B. In addition, the subjective evaluation of the change in the number of chews was highest in group C. Self-monitoring of masticatory behavior by providing a target value and the degree of achievement for the number of chews using a wearable chewing counter with a behavioral change algorithm could promote effective change in masticatory behavior and lead to an increased number of chews.

    BACKGROUND: It has been widely recognized that mastication behaviors are related to the health of the whole body and to lifestyle-related diseases. However, many studies were based on subjective questionnaires or were limited to small-scale research in the laboratory due to the lack of a device for measuring mastication behaviors during the daily meal objectively. Recently, a small wearable masticatory counter device, called bitescan (Sharp Co), for measuring masticatory behavior was developed. This wearable device is designed to assess objective masticatory behavior by being worn on the ear in daily life. OBJECTIVE: This study aimed to investigate the relation between mastication behaviors in the laboratory and in daily meals and to clarify the difference in mastication behaviors between those with metabolic syndrome (MetS) and those without (non-MetS) measured using a wearable device. METHODS: A total of 99 healthy volunteers (50 men and 49 women, mean age 36.4 [SD 11.7] years) participated in this study. The mastication behaviors (ie, number of chews and bites, number of chews per bite, and chewing rate) were measured using a wearable ear-hung device. Mastication behaviors while eating a rice ball (100 g) in the laboratory and during usual meals for an entire day were monitored, and the daily energy intake was calculated. Participants' abdominal circumference, fasting glucose concentration, blood pressure, and serum lipids were also measured. Mastication behaviors in the laboratory and during meals for 1 entire day were compared. The participants were divided into 2 groups using the Japanese criteria for MetS (positive/negative for MetS or each MetS component), and mastication behaviors were compared. RESULTS: Mastication behaviors in the laboratory and during daily meals were significantly correlated (number of chews r=0.36; P<.001; number of bites r=0.49; P<.001; number of chews per bite r=0.33; P=.001; and chewing rate r=0.51; P<.001). Although a positive correlation was observed between the number of chews during the 1-day meals and energy intake (r=0.26, P=.009), the number of chews per calorie ingested was negatively correlated with energy intake (r=-0.32, P=.002). Of the 99 participants, 8 fit the criteria for MetS and 14 for pre-MetS. The number of chews and bites for a rice ball in the pre-MetS(+) group was significantly lower than the pre-MetS(-) group (P=.02 and P=.04, respectively). Additionally, scores for the positive abdominal circumference and hypertension subgroups were also less than the counterpart groups (P=.004 and P=.01 for chews, P=.006 and P=.02 for bites, respectively). The number of chews and bites for an entire day in the hypertension subgroup were significantly lower than in the other groups (P=.02 and P=.006). Furthermore, the positive abdominal circumference and hypertension subgroups showed lower numbers of chews per calorie ingested for 1-day meals (P=.03 and P=.02, respectively). CONCLUSIONS: These results suggest a relationship between masticatory behaviors in the laboratory and those during daily meals and that masticatory behaviors are associated with MetS and MetS components.

    Numerous studies have evaluated the relationship between eating behavior and obesity, however few studies have objectively assessed eating behavior. Additionally, the association of masticatory behaviors with masticatory performance remains unclear. This study aimed to verify the relationship between masticatory performance and behavior measured by a wearable masticatory counter, and BMI. 365 healthy adults participated. Mastication behaviors, i.e. number of chews and bites, chewing rate, and chewing time, were measured using wearable masticatory counter while consuming one rice ball (100 g). Masticatory performance was evaluated using testing gummy jelly. Lifestyle habits including exercise, walking, and breakfast, were surveyed by questionnaire. The correlation coefficients between masticatory behaviors and performance and BMI were analyzed. Furthermore, multiple regression analysis was performed. The number of chews showed positive correlation with chewing rate, number of bites and chewing time, but no correlation with masticatory performance. BMI had weak but significant negative correlation with number of chews, bites, chewing time, and masticatory performance, but had no correlation with chewing rate. Multiple regression analysis revealed that BMI was associated with sex, age, number of chews, bites, masticatory performance, and walking speed. In conclusion, masticatory behavior and performance were not interrelated, but both were independently associated with BMI weakly.

    Purpose In recent years, the chewing frequency, i.e., the number of chewing cycles, has decreased owing to changes in dietary habits. Although these changes may be related to complete body health, there is no evidence-based tool to measure the dietary habits. We developed a small ear-hung wearable device for monitoring mastication behavior. The device, worn on the ear pinna, allows the counting of the number of chewing cycles, and data are collected on a smartphone via Bluetooth. In this study, the reliability of the novel device was verified.Methods A total of 22 healthy volunteers participated in the study. During measurement, the subjects wore the novel wearable device on their right ear pinna and were asked to chew gum, gummy jellies, and rice balls. The number of chewing cycles was counted by the device. A mandibular kinesiograph (MKG) was also recorded, and the chewing activity was recorded as a video. The accuracy, precision, and recall of the ear-hung device were calculated by comparing the data obtained from the MKG and the video recording. Additionally, the factors affecting reliability were examined.Results The accuracy, precision, and recall of the novel device were 101.6 ± 13.6%, 85.3 ± 11.0%, and 84.5 ± 9.5%, respectively. Although the accuracy was not affected by any factor, precision and recall of the novel device for women were significantly worse than that for men, and were greatest when the subjects were chewing gum.Conclusions Our findings suggest that the newly developed ear-hung wearable device for counting the number of chewing cycles was sufficiently reliable.

    咀嚼行動改善に対する啓発活動は多々行われているが、具体的な数値をもって咀嚼行動の改善を図る試みはほとんど行われていない。そこで、咀嚼回数計を使って自身の咀嚼行動を認識し、その問題点や改善点を考え、自発的な咀嚼習慣の行動変容を目指す「かむを測り、気づき、変えるための食育プロジェクト」を考案した。本研究の目的は、給食を用いて本プロジェクトを行い、発育期の児童に与える咀嚼行動変容効果を検討することである。対象は、新潟県内の1ヶ所の小学校5年生19名(男子7名、女子12名)とした。まず咀嚼回数計(シャープ社製bite-scan)を使用して3日間の給食時の咀嚼行動(咀嚼回数、一口あたりの咀嚼回数、食事時間、咀嚼テンポ、姿勢、動作の大きさ)を計測した。その後、咀嚼に関する授業を行うとともに最初の3日間の結果を配布して児童に自分の咀嚼行動の特徴について検討させた。さらに、各自が改善したい目標を掲げ次の5日間において咀嚼回数計を用いた介入を行った。最後に、3日間の給食を用いて再評価を行った。その結果、多くの児童たちは自身の咀嚼行動の長所と短所の両方に気づくことができた。また、介入後には咀嚼回数、食事時間、一口あたりの咀嚼回数、および咀嚼テンポは有意に増加し、姿勢、動作の大きさは有意に改善した。以上より、児童自身で立案した目標に向かって咀嚼行動変容を促した結果、効果的な行動変容を得ることができた。(著者抄録)

    食生活の変化によって咀嚼回数が減っていることが指摘されており、それに伴う「早食い」が肥満・糖尿病などの生活習慣病に与える影響が報告されている。しかし、日々の食事における食行動をモニタリングするツールは少なく、咀嚼行動に関する客観的なエビデンスは不足している。近年、センシング技術や通信技術の向上により、ウェアラブルデバイスによる咀嚼行動をモニタリングする試みがみられるようになってきた。われわれは、シャープ株式会社が開発したbitescanを使用して、日々の咀嚼行動を測定する研究を行っている。本装置は、患者本人が右耳にかけて使用し、スマートフォンと連動させて日常の咀嚼活動をモニタリングする。アプリケーションに行動変容を促す機能を付与したり、インターネットを介したデータの収集を行うこともできる。本総説では、bitescanの概要、精度を解説するとともに、これまでに開発されているさまざまなウェアラブルデバイスを用いた咀嚼行動モニタリングの試みを概説した。さらに、ウェアラブルデバイスを用いた咀嚼行動モニタリングの応用の可能性について検討した。(著者抄録)

    近年,咀嚼と全身の健康との関連が報告されているが,咀嚼能力と咀嚼行動(咀嚼回数やスピード)のいずれが全身の健康と関連するのかは不明瞭なままである.特に,医科で注目されている咀嚼行動に関しては,これまでアンケートによる主観的な評価にとどまっており,実効的なツールが無いことから,効果的な咀嚼行動変容を促すことができずにいた.そこで,我々は耳に掛けるだけで客観的に咀嚼行動のモニタリングが可能なウェアラブルデバイスの開発に携わってきた.本検討課題では,このデバイスを使用して成人期におけるにおける咀嚼能率と咀嚼回数,および全身との関連を明らかとし,行動変容アルゴリズムを用いて効果的な咀嚼行動変容を促すことにより,その改善効果を検討する.
    本年は,72名の対象者におにぎり1つ(100g)を摂取してもらい,その際の咀嚼回数,食事時間・咀嚼スピード・一口当たり咀嚼回数などを測定し,その後の経時的血糖値を計測した.さらに,対象者の身長体重測定,血液検査,口腔機能測定を行い,その関連について検討した.その結果,咀嚼回数は体重やBMI・腹囲と負の相関がみられ,経時的血糖変化曲線下面積(AUC)とは正の相関がみられた.また,摂取時間は咀嚼回数との相関が高く,体重・BMIとの負の相関がみられた.さらに,取り込み回数は体重・BMI・空腹時血糖と負の相関がみられた.一方で,一口当たりの咀嚼回数や咀嚼能率は体重やBMIとは相関を認めなかったが,経時血糖AUCとは正の相関を認めた.また,おにぎり咀嚼回数の中央値(234.5回)で被験者をよく噛む群とあまり咬まない群の2群に分けて比較したところ,体重,BMIには有意に差が見られ,あまり咬まない群は肥満の傾向が認められた.また,経時的血糖曲線におけるAUCの比較では,よく咬む群の方が有意に高い値となった.
