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.

Rupee falls 8 paise to hit all-time low of 84.50 against US dollar
Mumbai, Nov 21: The rupee depreciated 8 paise to settle at an all-time low of 84.50 against the US dollar on Thursday, dragged down by massive sell-off in domestic equity markets and surging crude oil prices amid a volatile geopolitical situation.
According to forex traders, the American currency strengthened due to safe-haven appeal amid escalating tension between Russia and Ukraine, while the continuous outflow of foreign funds also put pressure on the domestic unit.
At the interbank foreign exchange, the rupee opened at 84.41 and touched the lowest-ever level of 84.51 against the greenback during intra-day. The unit ended the session at 84.50 against the dollar, surpassing its previous all-time low closing level of 84.46 recorded on November 14.
On Tuesday, the rupee had settled flat at 84.42 against the US dollar.
The foreign exchange market was closed on Wednesday on account of assembly elections in Maharashtra.
"We expect the rupee to trade around 84.5 against the dollar by end December. A strong dollar continues to create a depreciating bias for currencies globally and is likely to sustain FPI outflows from Indian markets in the near-term.
"However, interventions by the Reserve Bank of India (RBI), supported by India's healthy foreign exchange reserves, should help keep rupee volatility in check," said Rajani Sinha, Chief Economist, CareEdge Ratings.
FPIs have withdrawn approximately USD 4 billion from Indian markets in November, following a record USD 11 billion in outflows in October. While high US Treasury yields and a strong dollar have contributed to these outflows, other domestic factors have also been at play, such as muted corporate earnings and high valuations.
"Over the medium-term, we expect the rupee to trade around 84 by the end of FY25, supported by India's strong fundamentals, including a manageable current account deficit, inclusion in global bond indices, fiscal consolidation and stronger growth relative to other emerging markets. These factors should help maintain India's attractiveness as an investment destination," Sinha added.
Sinha further said "going forward, it will be crucial to monitor the implementation of Trump's policies and China's response, as these will play a key role in shaping market dynamics."
Meanwhile, the dollar index, which gauges the greenback's strength against a basket of six currencies, was trading lower by 0.02 per cent at 106.66.
Brent crude, the global oil benchmark, surged by 1.84 per cent to USD 74.15 per barrel in futures trade.
Jateen Trivedi, VP Research Analyst - Commodity and Currency, LKP Securities, said the rupee weakened as pressure mounted due to the dollar scaling higher above 106.65 amidst renewed global uncertainties with geopolitical tensions between Russia and Ukraine adding to global risk aversion.
At the same time, sell-off in domestic equity markets was fuelled after the Adani Group faced bribery and fraud charges in the US. "This has further fuelled FII outflows, continuing the trend of capital flight from Indian markets," Trivedi said.
In the domestic equity market, the 30-share BSE Sensex tumbled 422.59 points, or 0.54 per cent, to close at 77,155.79 points, while Nifty tanked 168.60 points, or 0.72 per cent, to settle at 23,349.90 points.
Foreign Institutional Investors (FIIs) were net sellers in the capital markets on Thursday, as they offloaded shares worth Rs 5,320.68 crore, according to exchange data.
