EVALUATION OF SODIUM EXCRETION AND DIETARY INTAKE VIA A NEW SODIUM FOOD FREQUENCY QUESTIONNAIRE

DETERMINATION OF URINARY SODIUM EXCRETION AND DIETARY SODIUM INTAKE IN ADULTS BY DEVELOPING A FOOD FREQUENCY QUESTIONNAIRE FOR ADDED-SALT FOODS Dear Participant, A doctoral thesis study titled "Determination of Urinary Sodium Excretion and Dietary Sodium Intake in Adults by Developing a Food Frequency Questionnaire for Added-Salt Foods" is being conducted by Ayşe Gökçe Alp, a PhD student in the Department of Nutrition and Dietetics at Hasan Kalyoncu University. The valuable contributions of participants are expected, and participation in the study is requested. No fee will be requested from participants for participation in this study, and no payment will be made to participants. The investigators thank participants in advance for their cooperation. The questionnaire has been designed to determine participants' general information (such as age, occupation, and marital status), nutritional habits (such as number of meals and meal-skipping status), food consumption status, food preferences, and lifestyle (such as physical activity level). In addition, height, body weight, and various circumference measurements (waist, hip, neck) will be taken by the researcher. Within the scope of the study, 24-hour and spot (one-time) urine samples will be collected. For the 24-hour urine collection process, after the first morning urine is discarded, all urine produced during the day - starting with the second urination and including the first urination of the following day - will be collected. The 24-hour urine collection will take place on the second day of the food consumption record period; after the first urine is discarded, all urine collected throughout the day will be delivered to the researcher on the third day. Urine samples must be stored in a dark, cool environment at home. The spot urine sample will be collected on the third day, at the same time as the food consumption records and anthropometric measurements are taken. The responses provided by participants will be kept strictly confidential, will be used solely for scientific purposes, and will not be used outside the scope of this research.

Measuring Communal Coping in Dual-smoking Couples Making a Quit Attempt

Smoking is the leading preventable cause of death in the United States, and quitting is especially difficult for couples who both smoke. When both partners smoke, they are less likely to quit successfully and more likely to relapse compared to people whose partner does not smoke. Research suggests that the way romantic partners interact and support each other during a quit attempt can make a real difference - but researchers do not yet know enough about what kinds of support actually help. This study examines a concept called "communal coping," which refers to when partners treat a shared health challenge - like quitting smoking - as something they are facing together as a team rather than as separate individuals. Researchers believe that couples who approach quitting this way may have better outcomes. To study this, researchers will ask both members of dual-smoking couples to complete brief daily surveys over two weeks while making a quit attempt. These surveys will track how partners support (or discourage) each other's quitting efforts on a day-to-day basis, along with cigarette use, cravings, and stress. This will help researchers understand which relationship patterns are most helpful for quitting, and identify specific targets for future couples-based smoking cessation programs.

Quitting Matters Human Immunodeficiency Virus Hybrid Trial

The purpose of this study is to compare the advantages and disadvantages of two approaches for quitting smoking among people living with HIV (PWH). Participants will complete a 24- week (\~6-month) study where the Participants will be assigned to one of two smartphone apps to help with quitting smoking. Regardless of the group participants are assigned to, they will also receive a combination of nicotine replacement therapy (patches and gums) that have been shown to help people quit smoking. The main questions this study aims to answer are: Participants will complete 5 video call visits over about 6 months. Participants will install their assigned smoking cessation app onto their phone and will be asked to use the app for the duration of the study along with their provided Nicotine Replacement Therapy (NRT) products. During the study visits, participants will meet with study staff to complete questionnaires and interviews. Participants may be asked to provide breath and saliva samples to measure the level of carbon monoxide and nicotine.
