Exposure to traffic noises may up obesity risk, claims Study

London, Nov 19: People who are exposed to road traffic noise for prolonged periods may be at increased risk of obesity, a study has found.

The study, published in the journal Environment International, was based on data from 3,796 adults.

"Our analysis shows that people exposed to the highest levels of traffic noise are at greater risk of being obese," said Maria Foraster, from Barcelona Institute for Global Health (ISGlobal) in Spain.

"For example, we observed that a 10-decibel increase in mean noise level was associated with a 17 per cent increase in obesity," said Foraster.

Researchers also analysed exposure to noise generated by aircraft and railway traffic and found no significant associations except in the case of long-term exposure to railway noise, which was associated with a higher risk of overweight but not of obesity.

The methodology and design of the study were chosen to allow the authors to look at the data from two different perspectives.

Cross-sectional analysis was used to study the participant population at a specific time point in the study and to examine more objective measures.

The longitudinal design, on the other hand, allowed the authors to evaluate how the risk of obesity evolved over the study period.

The associations with traffic-related noise pollution were consistent in both cases. Overweight was only associated with exposure to traffic-related noise in the cross-sectional analysis.

Researchers found no association between noise exposure and body mass index measured continuously throughout the longitudinal analysis.

"Our study contributes additional evidence to support the hypothesis that traffic-related noise affects obesity because the results we obtained in a different population were the same as those reported by the authors of earlier studies," said Foraster.

Sustained exposure to noise pollution is a widespread public health problem that is more serious than previously thought, researchers said.

Noise generates stress and affects our sleep. It alters hormone levels and increases blood pressure. Moreover, among other effects, sleep disturbance deregulates glucose metabolism and alters the appetite.

"In the long term, these effects could give rise to chronic physiological alterations, which would explain the proven association between persistent exposure to traffic-related noise and cardiovascular disease or the more recently discovered associations with diabetes and obesity," said Foraster.

"Our findings suggest that reducing traffic-related noise could also be a way of combating the obesity epidemic," she said.

Congress workers protested outside the home of Nilesh Kumbhani, the party's candidate from Gujarat's Surat Lok Sabha seat whose nomination form was rejected due to alleged discrepancies, as he was likely to join the BJP, sources said on Tuesday.

The protest came a day after the BJP's Mukesh Dalal was declared the winner from the party stronghold following the withdrawal of all the other eight candidates in the fray.

The sources said that the protesters called Kumbhani a "traitor" and "killer of democracy", adding that he could join the BJP as early as this week.

Kumbhani's nomination form was rejected after he was unable to present even one of his three proposers before Returning Officer Sourabh Pardhi.

The BJP had raised questions about the discrepancies in the signatures of three proposers in his nomination form.

The nomination form of Suresh Padsala, the Congress' substitute candidate from Surat, was also invalidated, pushing the party out of the poll fray in the BJP stronghold.

In his order, Pardhi said the four nomination forms submitted by Kumbhani and Padsala were rejected because at first sight, discrepancies were found in the signatures of the proposers, and they did not appear genuine.

The Lok Sabha elections in the Surat seat was supposed to take place on May 7.

The genocidal Israeli war on the Gaza Strip has entered its 200th day, with occupation forces killing more Palestinians in defiance of widespread international outcry to end the carnage.

The aggression marked its 200th day on Tuesday with no end in sight to the Israeli war that has so far killed a shocking number of Palestinians and led to a humanitarian crisis in the besieged territory.

The Gaza Health Ministry said Israeli forces have committed three "massacres" over the past 24 hours, killing at least 32 Palestinians and wounding 59 others.

The numbers, it added, bring the Palestinian death toll to more than 34,183, with at least 77,143 injured and an estimated 7,000 missing and presumed dead since early October.

More than 14,500 children and 9,500 women are among those killed, making up over 70 percent of the victims, according to health officials.

Israel waged its brutal US-backed war on the Gaza Strip on October 7 after the Palestinian Hamas resistance group carried out Operation Al-Aqsa Storm against the usurping entity in retaliation for its intensified atrocities against the Palestinian people.

Israel has been carrying out war crimes in Gaza by deliberately starving people and forcing their evacuation, as well as targeting hospitals and schools sheltering displaced Palestinians.

Despite all these atrocities, the regime has failed to achieve its declared objectives of “destroying Hamas” and finding Israeli captives held in Gaza.

The Karnataka government's decision to categorise the entire Muslim community as a backward caste for reservation purposes in the state has drawn criticism from the National Commission for Backward Classes (NCBC), which said such blanket categorisation undermines the principles of social justice.

According to the data submitted by the Karnataka Backward Classes Welfare Department, all castes and communities within the Muslim religion have been enlisted as socially and educationally backward classes under Category IIB in the State List of Backward Classes.

The NCBC, during a field visit last year, examined the state's reservation policy for OBCs in educational institutions and government jobs.

"All castes/communities of Muslim religion of Karnataka are being treated as socially and educationally backward classes of citizens and listed as Muslim Caste separately under Category IIB in the State List of Backward Classes for providing them reservation in admission into educational institutions and in appointments to posts and vacancies in the services of the State for the purpose of Articles 15(4) and 16(4) of the Constitution of India," the NCBC said in a statement on Monday night.

This categorisation has led to the provision of reservation benefits for 17 socially and educationally backward castes under Category I and 19 castes under Category II-A, respectively.

The NCBC said the blanket categorisation of Muslims as a backward caste undermines the principles of social justice, particularly for the marginalised Muslim castes and communities identified as socially and educationally backward.

However, the NCBC emphasised that while there are indeed underprivileged and historically marginalised sections within the Muslim community, treating the entire religion as backward overlooks the diversity and complexities within Muslim society.

"The religion-based reservation affects and works against ethics of social justice for categorically downtrodden Muslim castes/communities and identified socially and educationally backward Muslim castes/communities under Category-I (17 Muslim castes) and Category II-A (19 Muslim castes) of State List of Backward Classes. Hence, socially and educationally backward castes/communities cannot be treated at par with an entire religion," the NCBC stated.

The NCBC also voiced concern over the impact of such reservations on the overall framework of social justice, particularly in the context of local body polls.

While Karnataka provides 32 per cent reservation to backward classes in local body elections, including Muslims, the Commission stressed the need for a nuanced approach that accounts for the diversity within these communities.

According to the 2011 Census, Muslims constitute 12.92 per cent of the population in Karnataka.
