New research confirms: Abdominal width and handshake strength are health risk indicators

A new study has confirmed that waist width and grip strength are indicators of health risk. Researchers have found that these two simple measurements can better predict the likelihood of premature death than body mass index (BMI). The findings were published in The Archives of Gerontology and Geriatrics after analyzing data from nearly 5,674 adults in the United States over almost seven years. During this period, 373 participants died. Those with larger waists and weaker grip strength had nearly double the risk of death compared to those without these characteristics. The link remained consistent regardless of age, socioeconomic status, lifestyle habits, or existing medical conditions. The study did not directly measure fat levels but instead used waist circumference as a proxy for visceral fat, the dangerous type of fat that accumulates around internal organs. Grip strength was considered an indicator of overall physical frailty, especially among individuals with higher body weight. When both factors were combined, the risk increased significantly. Participants with both a large waist and weak grip strength had a 97% greater risk of death than those without either characteristic. While the study highlights the importance of these measurements, experts caution that BMI should not be discarded entirely. Dr. Bryan Blissmer, a kinesiologist at the University of Rhode Island, noted that BMI remains a useful tool but should always be evaluated alongside other metrics such as waist size, changes in body composition, physical function, and general well-being. His recent research even suggested that BMI indicating overweight might actually reduce mortality rates in both genders. However, no single measurement can fully predict future health outcomes. Therefore, further evidence is needed before routine clinical practices include measuring waist size and assessing grip strength. Separately, another study has challenged common beliefs about drinking water during meals. It suggests that consuming more water while eating may lead to increased food intake rather than reduced calorie consumption. The research, published in Appetite, found that participants who drank more water during meals consumed approximately 40 grams, about 50 additional kilocalories, of extra food for each 100 milliliters of water. This effect was observed even among those who frequently alternated sips with bites. While the study does not prove that water directly causes increased food intake, it raises questions about the effectiveness of drinking water as a strategy for weight control. Possible explanations include the role of water in enhancing taste perception and prolonging the enjoyment of food, which could delay the decision to stop eating. Water may also facilitate chewing and swallowing, potentially speeding up meal consumption. However, the study emphasizes that the relationship between water intake and food consumption is still under investigation. Further research will be needed to determine whether the effects are direct or influenced by other variables such as meal duration or individual differences in satiety signals. For now, the findings serve as a reminder that the impact of drinking water during meals may be more complex than previously assumed.
