Weight loss in elderly may harm bone strength
New York, June 3 : While losing excess weight can be considered healthy, researchers claim that it may reduce bone density, bone architecture and bone strength in older adults.
According to the study, the magnitude of changes to the skeleton were clinically significant and translated into an almost three-fold increase in the risk of fracture for those who lost five per cent or more weight over 40 years.
Long-term and recent weight loss were found to be associated with lower cortical density and thickness, higher cortical porosity, and lower trabecular density and number in the elderly.
"We showed that men and women with both shorter term weight loss over 4-6 years and longer term weight loss over 40 years had more micro-architectural deterioration of their bones than persons who did not lose weight," said principal investigator Douglas P. Kiel from the Hebrew Seniorlife Institute for Aging Research, US
The study published in the Journal of Bone and Mineral Research, included 769 women, 595 men with an average age of 70.
Weight measurements taken every 4-6 years were used to assess recent weight change over 6 years and long-term change over 40 years.
"Older adults who are losing weight should be aware of the potential negative effects on the skeleton and may want to consider counteracting these effects through interventions such as weight-bearing exercise and eating a balanced diet," said senior author, Elizabeth Samelson.
"Given that weight loss is highly common in older adults, further work is needed to evaluate if these bone deficits can be prevented through interventions or therapy," Samelson noted.

Consumers feeling the heat of rising tender coconut prices in Karnataka
Bengaluru: The cost of tender coconuts has skyrocketed in Karnataka, with retail prices now ranging between Rs 50 and Rs 60 per coconut. In parts of North India, prices have even touched Rs 80 to Rs 100. This price hike is reportedly attributed to a combination of extreme temperatures in Northern India and lower yields in Karnataka, which has been facing its own heatwave.
Maddur, the largest market for tender coconuts in India, has seen average wholesale prices fluctuating between Rs 38 and Rs 50 per coconut over the past three months. Retail prices are higher and depend upon distance from key markets such as Davangere, Tumakuru, Mandya, Hassan, and others as reported by Deccan Herald on Saturday.
During June and July of this year, tender coconuts were available for around Rs 35 in Karnataka, the country's leading coconut producer. However, prices have spiked due to a variety of factors. According to the state government's online agriculture marketing information website, Krishi Marata Vahini, wholesale prices have risen by at least Rs 10,000 per 1,000 coconuts compared to last year.
V. Rajannab, Deputy Director of the Tumakuru APMC Yard, attributed the supply disruption to the "heatwave conditions of the summer of 2024," explaining that farmers could harvest only 30% to 40% of their expected yield. He told the news outlet that the increased demand from North Indian states has further driven up prices in the local market. Nearly 60% of Karnataka's tender coconuts are shipped to North India, with states like Jammu and Kashmir and Gujarat now seeking supplies, he added.
Officials from the horticulture department have suggested that the high price of ball copra could also have impacted the supply of tender coconut. “The price of ball copra has more than doubled in the last three months, going from Rs 8,000 to Rs 18,000 a tonne. There is a general feeling that the price could go further high, which is why most of the farmers are not harvesting tender coconuts,” Horticulture Deputy Director Kadiregowda was quoted as saying by DH.
However, there is some hope for price relief in the near future. With copious rains this monsoon, the yield is anticipated to improve, which could further help stabilise the market and bring prices down in the coming weeks.
