The studies look at people over a long period of time.
Transfats weren't commonly recognized as a problem until, what, 2006? Both of the studies looked at periods ending in 2012: This cohort study investigated 83 349 women from the Nurses’ Health Study (July 1, 1980, to June 30, 2012) and 42 884 men from the Health Professionals Follow-up Study (February 1, 1986, to January 31, 2012) The questionaires for the latter study are here. Click on the "Diet" tab in the table. The questions seem reasonable, but of course, they're not comprehensive, and people have to estimate (unless they're keeping a journal (and I think I read somewhere that many people do). I think everyone agrees that it's not ideal, but it's a lot of data and they've tried to make the data as broadly useful as possible. The problems with trying to document everything about a diet, and try to have enough people eat a particular diet to test various hypotheses are obvious. Presumably they have enough data to separate out trans-fats from saturated fats, at least in some cases. I would be surprised if those results were different from the general consensus now. FWIW. :-) Cheers, Scott.

As bad as I thought
Let's assume I'm trying as hard as I can to be honest and thorough. I keep track of absolutely everything I eat. I want to fill this out accurately. I've just eaten a Lean-Cuisine Creamy Basil Chicken with Tortellini. The ingredients are: skim milk, low fat asiago cheese tortellini (enriched extra fancy durum flour and semolina [durum wheat flour, semolina, niacin, iron {ferrous sulfate}, thiamin mononitrate, riboflavin, folic acid], water, fat free ricotta cheese [pasteurized whey, pasteurized skim milk, vinegar, xanthan gum, vitamin a palmitate], whole eggs, asiago cheese [pasteurized milk, cheese cultures, salt, enzymes], bread crumbs [wheat flour], skim milk with vitamin a added, parmesan cheese [pasteurized part skim milk, cheese cultures, salt, enzymes], romano cheese made from cow's milk [pasteurized milk, cheese cultures, salt, enzymes], cooked onions, low moisture part skim mozzarella cheese [pasteurized milk, cheese cultures, salt, enzymes], butter [cream, salt], brown sugar [sugar, cane syrups], white distilled vinegar [white distilled vinegar, water], roasted garlic, cooked garlic, spices, salt, modified cornstarch, beta carotene), cooked white meat chicken (white meat chicken, water, modified tapioca starch, chicken flavor [dried chicken broth, chicken powder, natural flavor], carrageenan, whey protein concentrate, soybean oil, corn syrup solids, sodium phosphate, salt), italian green beans, water, yellow carrots, red peppers, 2% or less of cream, modified cornstarch, parmesan cheese paste (granular and parmesan cheese [pasteurized milk, cheese cultures, salt, enzymes], water, salt, lactic acid, citric acid), basil, garlic puree, potato starch, sea salt, butter (cream, salt), dried cream extract, yeast extract, potassium chloride, spice, xanthan gum, lactic acid, calcium lactate, seasoning (wheat starch, extracts of annatto and turmeric color, natural flavor). How do I fill out the survey for that? Back in the 50s you could probably ask a housewife what their family ate that week and she could figure it out with a little work. Today? Good luck. Which, by the way, would actually be a great survey: How often do you cook from scratch vs. prepared heat-and-eat foods, and how does that correlate with health?
