본 연구는 중년(40∼50대)여성에게 청국장 식이와 등마사지가 피부와 체형에 어떠한 영향을 미치는지에 관한 연구이다. 연구 대상자들은 대조군10명, 청국장을 섭취하는군 10명, 등마사지를 실시하는군 10명, 청국장 식이와 등마사지를 복합으로 실시하는 복합군 10명을 각각 네 개의 그룹으로 나누어 총 12주 동안 임상실험하였다. 연구 대상자들은 매일 아침 공복에 생청국장 50g(콩45∼50개 정도:낱개포장)을 식이하였으며 등마사지는 주 2회 30분씩 총 24회 동일한 관리사가 관리하도록 하였다. 실험 전후 안면과 목피부의 유분, 수분, pH, 멜라닌, 홍반, 명도, 적색도, 황색도와 체형의 체중, 체지방량, 골격근량, BMI, 체지방률, WHR을 측정 비교한 결과 안면피부의 경우 대조군은 유분 12%, 수분 2%, 멜라닌 2%, 적색도 7%, 황색도 12% 유의적으로 증가하였고 명도 1% 유의적으로 감소하였으며 pH, 홍반에는 유의적인 변화가 없었다. 청국장 식이군은 유분 11%, 수분 3%, 명도 2% 유의적으로 증가하였고 멜라닌 2%, 홍반 1%, 적색도 5%, 유의적으로 감소하였으며 pH, 황색도에는 유의적인 변화가 없었다. 등마사지군은 유분 24%, 수분 5%, 명도 3% 유의적으로 증가하였고 pH 3%, 멜라닌 8%, 홍반 8%, 적색도 9% 유의적으로 감소하였으며 황색도에서는 유의적인 변화가 없었다. 복합군은 유분 23%, 수분 9%, 명도 5% 유의적으로 증가하였고 멜라닌 13%, 적색도 7%, 황색도 2% 유의적으로 감소하였으며 pH, 홍반에는 유의적인 변화가 없었다. 안면피부는 내인성과 외인성의 노화로 인한 유, 수분량, 색소 상태 등 피부상태가 두드러지게 표현되는 부위로 실험 후 피부 측정 결과 대조군과 차이가 나는 것을 확인할 수 있었다. 목 피부의 경우 대조군은 유분 16%, 수분 2%, 멜라닌 2%, 홍반 1%, 적색도 4% 유의적으로 증가하였고 pH 3%, 명도 1% 유의적으로 감소하였다. 청국장 식이군은 유분 18%, 수분 3%, 명도 2% 유의적으로 증가하였고 pH 5%, 멜라닌 5%, 적색도 3%, 황색도 1% 유의적으로 감소하였으며 홍반에서는 유의적인 변화가 없었다. 등마사지군은 유분 38%, 수분 4%, 명도 3% 유의적으로 증가하였고 pH 5%, 홍반 4%, 적색도 7%, 황색도 3% 유의적으로 감소하였으며 멜라닌에서는 유의적인 변화가 없었다. 복합군은 유분 34%, 수분 3%, 명도 4% 유의적으로 증가하였고 pH 7%, 멜라닌 11%, 홍반 5%, 적색도 10%, 황색도 3% 유의적으로 감소하였다. 체형의 경우 대조군은 BMI 2%, 체지방률 1% 유의적으로 증가하였으며 나머지 체중, 체지방량, 골격근량, WHR에서는 유의적인 변화가 없었다. 청국장 식이군은 체중 2%, 체지방률 1% 유의적으로 감소하였고 골격근량 3% 유의적으로 증가하였으며 체지방량, WHR에서는 유의적인 변화가 없었다. 등마사지군은 체중 3%, BMI 3%, 체지방률 1% 유의적으로 감소하였으며 체지방량, WHR, 골격근량에는 유의적인 변화가 없었다. 복합군은 체중 6%, 체지방량 5%, BMI 5%, 체지방률 3%, WHR 4% 유의적으로 감소하였고 골격근량 4% 유의적으로 증가하였다. 이 연구를 통하여 안면피부와 목 피부, 체형의 변화에 대조군에 비해 청국장 식이군과 등마사지군이 효과가 좋았으나 이 두가지를 복합적으로 실시하였을 때 효과가 더욱 좋은 것으로 나타났다. 이런 결과를 도출하게 된 가장 주된 원인은 청국장의 다양한 생리활성성분의 흡수를 촉진할 수 있도록 등마사지가 효과적으로 작용하여 피부노화, 체지방 및 골격근량에 긍정적인 효과가 있었다고 생각한다. 이와 같이 본 논문의 유의적인 결과들을 토대로 분석하여 보면 청국장 식이에 다량 함유되어 있는 이소플라본 등의 각종 다양한 생리활성성분들의 부족현상과 갱년기의 시작과 과정 중으로 인한 인체 순환의 장애가 중년(40∼50대)여성에게 이미 시작되었다는 것을 뒷받침하여 준다. 따라서 갱년기와 노화에 따른 인체의 순환 장애와 여성호르몬 및 다양한 생리활성성분들의 관계를 체계적으로 임상설계하고 연구하여 상관관계가 정확히 밝혀진다면 피부 및 신체의 노화를 어느 정도 억제하고 웰빙적인 건강한 삶을 살 수 있는 방법이 제시될 것으로 생각된다.

This study is intended to look into the effects of cheonggukjang diet and back massage on skin and body shape of middle-aged women in their 40s and 50s. To achieve this, clinical trials were performed on 40 middle-aged women in their 40s and 50s for 12 weeks. They were divided into four groups such as control group (10 persons), cheonggukjang diet group (10 persons), back massage group (10 persons) and combined group of cheonggukjang diet and back massage (10 persons). They took 50g of unripe cheonggukjang diet(about 45∼50 beans: individual packaging) on an empty stomach every morning, and they got their back massaged by the same therapist total 24 times twice a week for 30 minutes. The comparative measurement of facial skin, neck skin and body shape before and after the experiment showed that there was a 12%, 2%, 2%, 7% and 12% significant increase in sebum, moisture, melanin, redness and yellowness of facial skin for the control group, respectively, but there was a 1% significant decrease in brightness, and there was no significant change in pH and erythema. For the cheonggukjang diet group, there was a 11%, 3% and 2% significant increase in sebum, moisture and brightness of facial skin, respectively. But there was a 2%, 1% and 5% significant decrease in melanin, erythema and redness, respectively, and there was no significant change in pH and yellowness. For the back massage group, there was a 24%, 5% and 3% significant increase in sebum, moisture and brightness of facial skin, respectively. But there was a 3%, 8%, 8% and 9% significant decrease in pH, melanin, erythema and redness, respectively, and there was no significant change in yellowness. For the combined group, there was a 23%, 9% and 5% significant increase in sebum, moisture and brightness of facial skin, respectively. But there was a 13%, 7% and 2% significant decrease in melanin, redness and yellowness, respectively, and there was no significant change in pH and erythema. The facial skin is the part that shows up the skin condition such as intrinsic and extrinsic aging-related sebum, moisture and pigment prominently, which the measurement of facial skin after the experiment is different than the control group. There was a 16%, 2%, 2%, 1% and 4% significant increase in sebum, moisture, melanin, erythema and redness of neck skin for the control group, respectively. But there was a 3% and 1% significant decrease in pH and brightness, respectively. For the cheonggukjang diet group, there was a 18%, 3% and 2% significant increase in sebum, moisture and brightness of neck skin, respectively. But there was a 5%, 5%, 3% and 1% significant decrease in pH, melanin, redness and yellowness, respectively, and there was no significant change in erythema. For the back massage group, there was a 38%, 4% and 3% significant increase in sebum, moisture and brightness of neck skin, respectively. But there was a 5%, 4%, 7% and 3% significant decrease in pH, erythema, redness and yellowness, respectively, and there was no significant change in melanin. For the combined group, there was a 34%, 3% and 4% significant increase in sebum, moisture and brightness of neck skin, respectively. But there was a 7%, 11%, 5%, 10% and 3% significant decrease in pH, melanin, erythema, redness and yellowness, respectively. There was a 2% and 1% significant increase in BMI and body fat percentage of body shape for the control group, respectively. But there was no significant change in weight, body fat mass, skeletal muscle mass and WHR. For the cheonggukjang diet group, there was a 2% and 1% significant decrease in weight and body fat percentage of body shape for the control group, respectively. But there was a 3% significant increase in skeletal muscle mass, and there was no significant change in body fat mass and WHR. For the back massage group, there was a 3%, 3% and 1% significant decrease in weight, BMI and body fat percentage, respectively. But there was no significant change in body fat mass, WHR and skeletal muscle mass. For the combined group, there was a 6%, 5%, 5%, 3% and 4% significant decrease in weight, body fat mass, BMI, body fat percentage and WHR, respectively, but there was a 4% significant increase in skeletal muscle mass. As for the results of this study, the cheonggukjang diet group and the back massage group were more effective in the change of facial skin, nect skin and body shape than the control group, but the combined group of cheonggukjang diet and back massage was the best effective. The leading reason for this result lies in the positive effect of back massage - which helps promote the absorption of various bioactive components in cheonggukjang diet - on skin aging, body fat mass and skeletal muscle mass. Based on the significant findings of this paper, it is said that the shortage of various bioactive components like isoflavone in cheonggukjang diet and human body circulation disturbance caused by the beginning and process of menopause have already begun among middle-aged women in their 40s and 50s. Consequently, the systematic clinical design and study on the relationship between human body circulation disturbance, female hormone and various bioactive components caused by menopause and aging in future will come up with ways to inhibit skin and body aging to some extent and live a healthy wellbeing life.
