Air pollution linked to poor bone health among Indians

Air Pollution

New Delhi: High level of air pollution may be weakening the bones of Indians, in addition to increasing risk for other health conditions such as lung cancer, stroke, respiratory diseases, warns a study.

The study analysed the association between air pollution and bone health in over 3,700 people from 28 villages outside the city of Hyberabad.

The results, published in the journal JAMA Network Open, showed that exposure to ambient air pollution, particularly to fine particles, was associated with lower levels of bone mass.

“This study contributes to the limited and inconclusive literature on air pollution and bone health,” said first author of the study Otavio Ranzani, researcher at Barcelona Institute for Global Health (ISGlobal) in Spain.

Regarding the possible mechanisms underlying this association, he said “inhalation of polluting particles could lead to bone mass loss through the oxidative stress and inflammation caused by air pollution”.

For the study, the authors used a locally-developed model to estimate outdoor exposure at residence to air pollution by fine particulate matter (suspended particles with a diameter of 2.5 micrometre or less) and black carbon.

The participants also filled a questionnaire on the type of fuel used for cooking. The authors linked this information with bone health assessed using a special type of radiography that measures bone density, called dual-energy x-ray absorptiometry, and measured bone mass at the lumbar spine and the left hip.

Annual average exposure to ambient PM2.5 was 32.8 micrograms per cubic metre air — far above the maximum levels recommended by the World Health Organisation (10 micrograms per cubic metre air).

The researchers found an association between exposure to air pollution and poor bone health. No correlation was found with use of biomass fuel for cooking.

Osteoporosis is a disease in which the density and quality of the bone is reduced. Globally, it is responsible for a substantial burden of disease and its prevalence is expected to increase due to ageing of the population.

Kanhaiya Kumar

New Delhi, Feb 29 : A day after Delhi government’s sanction to Delhi Police for the prosecution of former JNU student leader Kanhaiya Kumar and others in the 2016 sedition case, JNU Students Union (JNUSU) on Saturday was silent on the development.

Repeated calls and WhatsApp messages to Jawaharlal Nehru University Students Union President Aishe Ghosh and Vice-President Saket Moon went unanswered.

Union General Secretary Satish Chandra Yadav responded to the call and targeted Delhi Chief Minister Arvind Kejriwal over the decision, but maintained that these were his personal views and not of the JNUSU.

“The decision proves that Kejriwal projected just a fake image during the election campaign. The decision to not give any prosecution sanction before the campaigning ended was to protect his vote bank,” Satish said.

“Now that the Delhi Assembly elections are over, he has decided to betray us,” Satish claimed.

Asked if was speaking for the Union, Satish said, “I am out of the campus and unable to discuss with fellow JNUSU members. So these are my views,” he added.

The JNUSU has for long defended Kanhaiya, Umar Khalid and Anirban Bhattacharya.

On February 9, 2016, anti-national slogans were allegedly raised on the campus during a protest against the death sentence awarded to Afzal Guru in the 2002 Parliament attack.

The 1,200-page charge sheet filed by the Delhi Police Crime Branch named 10 JNU students, including Kanhaiya Kumar, Umar Khalid, Anirban Bhattacharya, and seven Kashmiri students as the main accused in the case.

Later JNUSU office-bearers maintained that these people were targeted on false charges and that the charge sheet was an effort by the BJP-led central government to muzzle students’ voice.

Delimitation Act 2002 in North East

New Delhi, Feb 29 : The decks have been cleared for the resumption of the delimitation exercise in four Northeastern states. The central government on Friday cancelled its earlier notifications which deferred delimitation in Assam, Nagaland, Manipur and Arunachal Pradesh due to security issues.

The delimitation exercise will redraw the boundaries of Assembly and Lok Sabha constituencies in the four states which have been hit by insurgency.

The rationale given by the government was that the exercise could be carried out “now” as the previous circumstances cease to exist.

The ”order” issued by the Legislative Department of the Law Ministry said “it appears that the circumstances that led to the deferring of the delimitation exercise” in Assam, Manipur, Arunachal Pradesh and Nagaland “have ceased to exist and that the delimitation of the constituencies as envisaged under the Delimitation Act, 2002 could be carried out now”.

It said now the President, satisfied that the circumstances that led to the deferring of the delimitation exercise have ceased to exist, “is pleased to rescind the notification … dated the February 8, 2008…”

The order pointed out that a Delimitation Commission was set up under the Delimitation Act, 2002 to readjust the division of each state and union territory into territorial constituencies for the purpose of Lok Sabha and state assembly elections on the basis of census figures of 2001.

The Commission completed the delimitation exercise and the Delimitation Order, 2008 in respect of all the states, except in these four northeastern states, it said.

Addressing all the four states individually, the order said the President on being satisfied that a situation had arisen where the unity and integrity of India was likely to be threatened and there was serious threat to the peace and public order, deferred the delimitation exercise.

“In India, such Delimitation Commissions have been constituted four times – in 1952 under the Delimitation Commission Act, 1952, in 1963 under Delimitation Commission Act, 1962, in 1973 under Delimitation Act, 1972 and in 2002 under Delimitation Act, 2002,” it said.
