![]() Demographic characteristics were obtained from a structured questionnaire. Physical examinations included body weight, height and body mass index (BMI) measurements. Informed consent was obtained from all participants. The protocols for KNHANES IV-V were approved by the Institutional Review Board (IRB) of the Korea Centers for Disease Control and Prevention (2010-02CON21-C, 2011-02CON-06-C) and the research was performed in compliance with the guidelines laid down in the Declaration of Helsinki. Finally, the current study included 8,732 subjects (3,590 men and 5,142 women) for analysis. An additional 940 participants with implausible energy intake based on dietary surveys ( 5,000 kcal/d) were also excluded. We defined postmenopausal status as not experiencing menstruation for > 12 months, and included surgical menopause. Among 9,677 subjects, we additionally excluded subject (n = 5) without BMD data in current study. According to this guideline, we selected postmenopausal women (n = 5,624) and men aged 50 years old and older (n = 4,053). The International Society for Clinical Densitometry recommends that osteoporosis be diagnosed in postmenopausal women, and in men aged 50 and older, if the T-score of the lumbar spine, total hip or femoral neck is −2.5 or less. ![]() Data were collected from the cross-sectional KNHANES study database, including from health interviews, health examinations, and nutrition surveys, as well as BMD examinations.Ī total of 21,303 participants were examined in KNHANES from 2008 to 2011. The current study was based on data from the KNHANES IV-V (2008-2011), which conducted bone mineral density examinations. These were cross-sectional and nationally representative surveys performed by the Division of Chronic Disease Surveillance, and the Korea Centers for Disease Control and Prevention. The KNHANES was conducted to investigate the health and nutritional status of Koreans from 1998 onwards. We also analyzed the correlation of potassium intake with bone mineral density (BMD). Hence, the current study aimed to identify the link between dietary potassium and the prevalence of osteoporosis and osteopenia in at-risk Koreans, using national survey data. It suggests that the positive effect of potassium could be through either suppressing calcium resorption or bone mineral dissolution or both. The potassium bicarbonate, but not sodium bicarbonate, reduced urinary calcium excretion in healthy men, and the potassium citrate reduced urinary calcium excretion in men with uric acid nephrolithiasis. In addition, increasing potassium intake increases urinary retention, reducing loss of calcium and thus creating a more positive calcium balance and inhibiting bone resorption. Thus, the alkaline potassium salt is thought to prevent bone resorption for pH homeostasis. Fruit and vegetable intake could balance this excess acidity by providing alkaline salts of potassium. ![]() ![]() The continual release of alkaline salts from bone for acid-base balance would cause bone loss and osteoporosis. The western diet including high meats and cereal grains produces a low-grade metabolic acidosis. The most facilitated hypothesis regarding to benefit of dietary potassium on bone health is through its effect on acid-base balance, even though the role of the skeleton in pH regulation is controversial. Recently, population-based observational studies have been identified beneficial effects of dietary potassium and fruit and vegetables on bone health. Even though diet play an important role in bone health, most studies has concentrated on single nutrients including calcium and vitamin D, or supplements containing these nutrients. ĭiet is a crucial modifiable factor that causes or contributes to osteoporosis and fractures. This trend is thought to be a result of a westernized dietary lifestyle in Korea, along with demographic and sociological factors. Among Korea, the prevalence of osteoporosis was 7.3% in male and 38.0% in female adults ≥ 50 years old in 2011 and it has continuously increased. Osteoporosis is particularly associated with age and thus impose a heavy burden on global public health for aging population.
