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.

Mangaluru: In a significant step to curb online hate and intimidation, Mangaluru City Police have registered a suo motu case against multiple Instagram accounts accused of circulating alleged provocative and threatening content.

While monitoring social media activity on Tuesday, Kankanady Town PSI Anitha Nikkam identified the Instagram handle ‘team_targetttt_900’ for posting a hate message alongside images of lethal weapons. Another account, ‘team_nagara_900’, allegedly shared a threatening post targeting activist Bharath Kumdelu, tagging additional pages such as KARAVALI-OFFICIAL.

Several other accounts — including ‘immu_bhai.fan’, ‘target_boy_900’, ‘kings_of_manglore’, ‘team_target_boys.900’, ‘arshad_mangalore’, ‘target_ka19_ullal’, ‘team_target__’, ‘troll_tigersz_900’, ‘tr_group_900’, and ‘team_target_900’ — are also under scrutiny for spreading similar inflammatory material, police said.

Authorities have urged citizens, especially young social media users, to report suspicious pages and avoid engaging with groups that glorify violence or threaten individuals. Online hate can quickly escalate into real-world harm, and police stress that sharing or promoting such content can attract legal consequences.

Bengaluru, Nov 26: Karnataka is taking its first concrete steps towards lifting a three-decade-old ban on student elections in colleges and universities. Deputy Chief Minister D.K. Shivakumar announced Wednesday that the state government will form a small committee to study the reintroduction of campus polls, a practice halted in 1989 following incidents of violence.

Speaking at a 'Constitution Day' event organised by the Karnataka Congress, Mr. Shivakumar underscored the move's aim: nurturing new political leadership from the grassroots.

"Recently, (Leader of the Opposition in Lok Sabha) Rahul Gandhi wrote a letter to me and Chief Minister (Siddaramaiah) asking us to think about restarting student elections," Shivakumar stated. "I'm announcing today that we'll form a small committee and seek a report on this."

Student elections were banned in Karnataka in 1989, largely due to concerns over violence and the infiltration of political party affiliates into campus life. The ban effectively extinguished vibrant student bodies and the pipeline of young leaders they often produced.

Mr. Shivakumar, who also serves as the Karnataka Congress president, said that former student leaders will be consulted to "study the pros and cons" of the re-introduction.

Acknowledging the history of the ban, he added, "There were many criminal activities taking place back then. We’ll see how we can conduct (student) elections by regulating such criminal activities."

The Deputy CM reminisced about his own journey, which began on campus. He recalled his political activism at Sri Jagadguru Renukacharya College leading to his first Assembly ticket in 1985 at the age of 23. "That's how student leadership was at the time. Such leadership has gone today. College elections have stopped," he lamented, adding that for many, college elections were "like a big movement" where leaders were forged.

The move, driven by the Congress high command's push to cultivate young talent, will face scrutiny from academics and university authorities who have, in the past, expressed concern that the return of polls could disrupt the peaceful academic environment and turn campuses into political battlegrounds.

Bengaluru, Nov 27: Karnataka Chief Minister Siddaramaiah’s camp is reportedly on alert as the Congress leadership tussle in the state intensifies, particularly amid speculation over the potential promotion of Deputy Chief Minister D.K. Shivakumar. Siddaramaiah is said to be in a “wait-and-watch” mode after admitting to “confusion” earlier this week and urging the party to “put a full stop” to it.

Sources say his supporters are ready to act if senior leaders — including party chief Mallikarjun Kharge, Sonia Gandhi, and Rahul Gandhi — give any indication of backing Shivakumar. If the party insists on a leadership change, Siddaramaiah’s camp has a list of alternatives, underscoring the deep rift between the two leaders. One possible candidate is Home Minister G. Parameshwara, a Siddaramaiah loyalist and influential Dalit leader.

The strategy was reportedly finalized at a meeting led by PWD Minister Satish Jarkiholi, another Siddaramaiah supporter, who stressed that Delhi leaders need to resolve the issue. Kharge and the Gandhis are expected to meet soon, after which Siddaramaiah and Shivakumar may be summoned to Delhi.

Shivakumar has largely stayed non-confrontational, publicly endorsing Siddaramaiah and downplaying speculation about his own ambitions. However, he has made pointed comments emphasizing the importance of honoring promises, directed at Siddaramaiah.

The feud traces back to the 2023 state election, when Siddaramaiah was chosen as Chief Minister while Shivakumar, who led the party’s campaign, was made Deputy CM and state party chief — a departure from the Congress’ usual “one post per person” rule.

There were also hints of a prior understanding that Siddaramaiah would step down midway through the term. As the halfway mark passed last week, Shivakumar-aligned lawmakers have ramped up pressure on the party for a leadership change, with Shivakumar himself hinting at stepping down as state party chief to pursue the top job.
